The correct answer is: Less reactive than benzyl chloride
Chlorobenzene is less reactive than benzyl chloride
In chlorobenzene the lone pairs present on $\mathrm{Cl}$ atom get involved in resonance with $\pi$ electrons of benzene due to which $C-C l$ bond acquires double bond character Hence, reactivity decreases.
