Solution

The correct option is B $4, 3$
$L i A l H_{4}$ van reduce aldehydes, ketones, esters, acylhalides, carboxylic acids, etc. while $N a B H_{4}$ can reduce aldehydes, ketones and some ester compounds.
So, here $L i A l H_{4}$ reduce $4$ groups (keto, aldo, acid, ester)
$N a B H_{4}$ reduce $3$ groups (keto, aldo, ester)
