Answer: 2. propylamine

Key idea: follow each step.

\(\mathrm{CH_3CH_2CH_2I+NaCN\to CH_3CH_2CH_2CN}\) (A, butanenitrile).
Partial hydrolysis with \(\mathrm{OH^-}\) gives \(\mathrm{CH_3CH_2CH_2CONH_2}\) (B, butanamide).
Hofmann bromamide reaction (\(\mathrm{Br_2/NaOH}\)) removes one carbon: \(\mathrm{CH_3CH_2CH_2NH_2}\).

C is propylamine, option 2.
