Which sentence is correct?

The correct answer is '1' i.e. She lives in an apartment.

Key Points

• The sentence correctly uses the preposition "in", which is appropriate to describe the location of living inside an apartment.
• Other options use incorrect prepositions or grammatical errors, making them invalid:
• Option 2: "She lives to an apartment" is incorrect because "to" is not the correct preposition to describe residence.
• Option 3: "She lives on an apartment" is incorrect as "on" implies being on top of something, which is not appropriate here.
• Option 4: "She live in apartment" is grammatically incorrect as the verb "live" does not agree with the subject "She" (missing "s" for singular third-person). Additionally, "apartment" should include the article "an".

Correct sentence: She lives in an apartment.

Additional Information

• Usage of Prepositions:
  • "In": Indicates being inside or enclosed within something. Example: She lives in a house.
  • "On": Indicates being on the surface of something. Example: The book is on the table.
  • "To": Indicates direction or movement toward something. Example: She is going to the park.
• Subject-Verb Agreement:
  • For singular third-person subjects like "She," the verb must include an "s" in the present tense. Example: She lives.
