Options

1. A
2. B(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{NH}_4+\mathrm{HNO}_2 \rightarrow \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH}+\mathrm{N}_2)
3. C$\mathrm{CH}_3 \mathrm{NH}_2+\mathrm{C}_6 \mathrm{H}_5 \mathrm{SO}_2 \mathrm{Cl} \rightarrow \mathrm{CH}_3 \mathrm{NHSO}_2 \mathrm{C}_6 \mathrm{H}_5$
4. D(\left(\mathrm{CH}_3\right)_2 \mathrm{NH}+\mathrm{NaNO}_2+\mathrm{HCl} \rightarrow \left(\mathrm{CH}_3\right)_2 \quad \mathrm{~N}-\mathrm{N}=0)
