The major product formed in the following reaction is

Why cannot aromatic primary amines be prepared by Gabriel phthalimide synthesis?

In a set of reactions,propionic acid yielded a compound $D$.
$CH_3CH_2COOH$ $\xrightarrow{SOCl_2} B$ $\xrightarrow{NH_3} C$ $\xrightarrow{KOH, Br_2} D$
The structure of $D$ would be

Which of the following can be prepared by the Gabriel phthalimide synthesis?

The product $(C)$ will be

Given below are two statements,one is labeled as Assertion $(A)$ and other is labeled as Reason $(R).$
Assertion $(A):$ Gabriel phthalimide synthesis cannot be used to prepare aromatic primary amines.
Reason $(R) :$ Aryl halides do not undergo nucleophilic substitution reaction.
