B. `H_(2)//Pd-BsSO_(4)`
C. `LiAIH_(4)//"ether"`
D. `NBH_(4)//"ether"//H_(2)O^(+)`

Answer

A

Explanation

It is stephen.s reaction.
`CH_(3)CH_(2)C-=N overset(HCl) to [CH_(3)CH_(2)C-=NH]^(+)Cl^(-) overset(SnCl_(2)//HCl) to [CH_(3)-CH_(2)CH=NH_(2)]^(+)SnCl_(6)^(2-) overset(H_(2)O//"boil") to CH_(3)CH_(2)CHO+NH_(4)Cl`
