HTML MCQ Quiz - Objective Question with Answer for HTML - Download Free PDF

Concept:

XML stands for extensible markup language which lets you define your own tags in the order they occur. It is derived from SGML (Standard Generalized markup language).

Explanation:

XML is a platform-independent language. It is used to store and organize the data. The first line in the XML document is the XML prolog which includes XML declaration, DOCTYPE, version and comments. XML documents must contain a root element. In XML1.0, all things in the prolog are optional while for version 1.1, declaration is required in the prolog.

Syntax for declaring the version of XML is :

XML is slightly different from HTML. In html, we have predefined tags, while in XML we have to define our own tags. XML .XML is used for storing and transporting the data. Using the XML sharing of data between two programs on different platforms is possible. 

Key Points

 The tag is used to embed an image in an HTML page. src - Specifies the path to the image. alt - Specifies an alternate text for the image, if the image for some reason cannot be displayed.

Syntax:

src Attribute= The required src attribute specifies the path (URL) to the image.

Example:

Hence the correct answer is src.

The correct answer is Option 2) It is possible to create custom tags in XML..

Key Points

• XML (eXtensible Markup Language) allows users to define their own custom tags that describe the data meaningfully.
• This flexibility is what makes XML powerful for data storage, transfer, and configuration.
• Unlike HTML, which has predefined tags, XML enables you to create tags that fit the context of your application — e.g., John.
• This makes XML widely used for configuration files, data interchange formats (e.g., between server and client), and more.

Additional Information

• Option 1 – Incorrect: XML can be used for interprocess communication, especially in web services and APIs (e.g., SOAP uses XML).
• Option 3 – Incorrect: Browsers already have built-in XML parsers. You don’t always need to create custom XML reader/writer classes.
• Option 4 – Incorrect: XML supports nesting of tags. In fact, proper nesting is required for XML to be well-formed.
• Key features of XML:
  • Custom tags
  • Hierarchical structure with nesting
  • Platform-independent data exchange
  • Strict syntax rules (must be well-formed)

The correct answer is option 4:

Key Points

• is the correct way to declare the document type in HTML5.
• It is a declaration that must appear at the very top of an HTML document, before the tag.
• It tells the web browser that the document is written in HTML5, ensuring proper rendering.
• It is not case-sensitive but is conventionally written in uppercase for clarity.

Additional Information

• Option 1 – : ❌ Incorrect syntax; HTML tags should be enclosed within <> and DOCTYPE is not a tag but a declaration.
• Option 2 – <\Doctype html>: ❌ Incorrect; uses an invalid backslash and incorrect capitalization.
• Option 3 – : ❌ Incomplete and incorrect declaration; not valid in HTML5.
• Option 4 – : ✅ Correct declaration for HTML5 documents.

Hence, the correct answer is: option 4:

The correct answer is CSS.

Key Points

• CSS (Cascading Style Sheets) is used to style and layout web pages—for example, to alter the font, color, size, and spacing of your content, split it into multiple columns, or add animations and other decorative features.
• CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript.
• It is the standard way to style web pages and is supported by all modern web browsers.

Additional Information

• Java++ - There is no programming language known as Java++. This option might be intended to confuse or check the aspirant's knowledge about programming languages.
• C++ - C++ is a general-purpose programming language created as an extension of the C programming language. It is used for developing desktop applications, games, and system software but not typically for styling web pages.
• Java - Java is a high-level, class-based, object-oriented programming language designed to have as few implementation dependencies as possible. It is commonly used for building application software, web applications, and large systems. However, it is not used for styling web pages.
