Correct Answer - B
First step yields nitroalkane which on reduction yields a primary amine
Nitroalkanes are obtained when we heat an alky1 halide with silver nitrite in agueous ethanolic solution
`RX + AgNO_(2)rarrRNO_(2)+RONO+AgX` This method is only useful for the preparation of primary nitroalkanes On account of competing elimination reaction the yield is about `15%` with sec-halides and `0-5%` with t-halides the yield decreases from primary to tertiary halides .
