$IV$. Sandmeyer reaction

Predict the product of the reaction: $C_6H_5NO_2 \xrightarrow{Fe/H_2O} \text{product}$

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.
In the light of the above statements,choose the correct answer from the options given below.
