The correct answer is:
$\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{Br}$
$\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{Br}$
$\mathrm{S}_{\mathrm{N}} 1$ reaction involves the formation of carbocation, so, more stable carbocation will have higher reactivity towards $\mathrm{S}_{\mathrm{N}} 1$ mechanism.
As $\mathrm{C}_6 \mathrm{H}_5{ }^{+} \mathrm{CH}_2$ is the most stabilised carbocation due to resonance, hence it will be most reactive towards $\mathrm{S}_{\mathrm{N}} 1$ mechanism.
