Answer 2

The reducing agent to be used is - (a) LiAlH₄/H₂O

Reducing agent is the compound that loses electron itself, and ends up oxidising other compound or element involved in the reaction.

The conversion mentioned in question is from acid to primary alcohol. The -COOH group is reduced to

-OH group.

Thus, strong reducing agent LiAlH₄/H₂O will be used. Diborane can also be used for the purpose of reduction of carboxylic acids, but it is primarily used for addition reaction
