The correct statement for the following reaction is

Concept:

Intramolecular hydride transfer is a chemical reaction where a hydrogen (hydride) atom is transferred within a single molecule, typically involving the movement of a hydride ion (H-) from one atom to another within the same molecule. 

intramolecular hydride transfer is commonly found during the reduction of carbonyl compounds (such as ketones or aldehydes) to alcohols. This process can occur through an intramolecular mechanism where a hydride ion is transferred from a neighboring atom within the same molecule to reduce the carbonyl group.

Explanation:

BH(OAc)₃ is a derivative of NaBH₄ reagent. Here oxygen atom of reactant replaces one of the OAc group of reagent and forms a chelated system.

Mechanism:

Conclusion:

Hence, a chiral product is formed by intramolecular hydride transfer.
