Question

Identify the correct pathway to convert propanoic acid to ethylamine. The reagent represented by $$A, B$$  and $$C$$ are \[C{{H}_{3}}C{{H}_{2}}COOH\xrightarrow{A}X\xrightarrow{B}\]     \[Y\xrightarrow{C}C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}\]

	$$A$$	$$B$$	$$C$$
(a)	$$Ca{\left( {OH} \right)_2}$$	Heat	$$Pt/{H_2}$$
(b)	$$SOC{l_2}$$	$$N{H_3}$$	$$B{r_2}/KOH$$
(c)	$$HN{O_2}$$	$$P + {I_2}$$	$$LiAl{H_4}$$
(d)	$$HCN$$	$$N{H_3}$$	$$B{r_2}/KOH$$
