The correct statements about the products B and C in the given reactions are
\(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH} \xrightarrow[\text { Anhy } \mathrm{ZnCl}_2]{\mathrm{HCl} /} \mathrm{A} \xrightarrow[\text { AgCN }]{\text { ethanolic }} \underset{\text { Minor }}{\mathrm{B}}+\underset{\text { Major }}{\mathrm{C}}\)
I. \(B\) and \(C\) are functional isomers
II. With \(\mathrm{H}_2 \mid\) Catalyst B gives \(1^{\circ}\) amine and C gives \(2^{\circ}\)
III. \(B\) on acid hydrolysis gives formic acid and \(C\) gives \(\mathrm{C}_3 \mathrm{H}_6 \mathrm{O}_2\)
IV. C forms isocyanate with HgO

1. A I & III
2. B II & III
3. C I, II & IV
4. D II, III & IV
