Solution

The correct option is B Ketone
$L i A l H_{4}$ acts as a reducing agent which reduces an aldehyde, ester and carboxylic acid by adding hydrogen atoms to it result in the formation of a primary alcohol.
Ketones react with reducing agents $L i A l H_{4}$ to get reduced to secondary alcohol.
