The correct answer is:
$ < 7$
Ammonium chloride is a salt of weak base $\left(\mathrm{NH}_3\right)$ and strong acid $(\mathrm{HCl})$ hence, it is acidic in nature.
$$
\begin{gathered}
\mathrm{NH}_3+\mathrm{HCl} \longrightarrow \mathrm{NH}_4 \mathrm{Cl} \\
\mathrm{pH} \text { of } \mathrm{NH}_4 \mathrm{Cl} < 7
\end{gathered}
$$

\mathrm{NH}_3+\mathrm{HCl} \longrightarrow \mathrm{NH}_4 \mathrm{Cl} \\
