Primary amine is not formed in the reaction of
I. hydrolysis of RCN
II. reduction of RCH = NOH
III. hydrolysis of RNC
IV. hydrolysis of `R CONH_2`
The correct answer is

Alkaline hydrolysis of R_(2)C Cl_(2) forms

The reaction of RCN with R'MgX, followed by hydrolysis gives

The reaction of RCN with R'MgX, followed by hydrolysis gives
