Solution

The correct options are
A
$H_{2} / P d$

B
$N a B H_{4}$

C
$L i A l H_{4}$

$H_{2} / P d$ , $L i A l H_{4}$ , $N a B H_{4}$ , reduce aldehyde into alcohol having the same number of alcohol whereas RMgX followed by hydrolysis reduces aldehyde into an alcohol having an extra ‘R’ (alkyl group) from Grignard reagent.
