What are X and Y in the following reactions ?
`X-underset((ii)H_(2)O)overset((i)LiAH_(4))(rarr)RCH_(2)NH_(2)overset(H_(2)//NI)larrY`

Options

A. `{:(" "X," "Y),(RCOoversetΘ(O)Noverset(oplus)NH_(4)," "RCH_(2)CN):}`
B. `{:(" "X," "Y),(RCN," "RCONH_(2)):}`
C. `{:(" "X," "Y),(RNHCH_(3)," "RCH_(2)NC):}`
D. `{:(" "X," "Y),(RCONH_(2)," "RCN):}`

Explanation

In the given reaction X is `RCONH_(2)` and Y is RCN
`RCONH_(2) underset((2)H_(2)O)overset((1)LiAlH_(4))rarrRCH_(2)NH_(2)overset(H_(2)//Ni)(larr) RCN`
`LiAlH_(4)` is a nucleophilic reducing agent used to reduce polar multipe bonds like CH=O. It reduces amides and nitrites to amines while catalyst like Ni gives catalytic hydrogenation and adds on hydrogen on the multiple bond.
