Identify Reagents a and B Required for the Following Transformation

Identify reagents A and B required for the following transformation of acyl groups:
$\mathrm { C } _ { 2 } \mathrm { H } _ { 5 } \mathrm { COOH } \stackrel { \mathbf { A } } { \rightarrow } \mathrm { C } _ { 2 } \mathrm { H } _ { 5 } \mathrm { COCl } \stackrel { \mathbf { B } } { \rightarrow } \mathrm { C } 2 \mathrm { H } _ { 5 } \mathrm { CONHCH } 3 + \mathrm { HCl }$

A) A = HCl; B = H₂NCH₃
B) A = NaCl; B = HCONHCH₃
C) A = SOCl₂; B = HCONHCH₃
D) A = NaCl; B = H₂NCH₃
E) A = SOCl₂; B = H₂NCH₃
