The conversion of propan-1-ol to n-butylamine involves the sequential addition of reagents. The correct sequential order of reagents is

A

(i) $$SOCl_2$$ (ii) KCN (iii) $$H_2/Ni$$, $$Na(Hg)/C_2H_5OH$$

B

(i) HCl (ii) $$H_2/Ni$$, $$Na(Hg)/C_2H_5OH$$

C

(i) $$SOCl_2$$ (ii) KCN (iii) $$CH_3NH_2$$

D

(i) HCl (ii) $$CH_3NH_2$$
