The correct answer is:
$\mathrm{C}_6 \mathrm{H}_5 \mathrm{OH} \quad \mathrm{H}_3 \mathrm{CCH}_2$
When an alkyl aryl ether is reacted with halogen acid $(H X)$, the products are always phenol and an alkyl halide.
$$
\begin{aligned}
\mathrm{C}_6 \mathrm{H}_5-\mathrm{O}-\mathrm{CH}_2- & \mathrm{CH}_3+\mathrm{HI} \stackrel{100 \mathrm{C}}{\longrightarrow} \\
& \mathrm{C}_6 \mathrm{H}_5 \mathrm{OH}+\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{I}
\end{aligned}
