Solution

The correct option is B CH3CH2CH2OH
CH3CH2CH2CONH2Ca(OH)2,Cl2−−−−−−−ΔCH3CH2CH2NH2XHNO2−−−CH3CH2CH2OHZ
The first step is the Hoffmann's bromamide reaction in which butanamide gives n-propyl amine which contains one carbon atom less.
In the second reaction, nitrous acid reacts with n-propyl amine to form n propyl alcohol.
