Which of the following amines cannot be prepared by the Gabriel phthalimide synthesis?

The Gabriel synthesis needs an ${\mathrm{S}}_{\mathrm{N}}2$ attack of phthalimide anion on an alkyl halide. Ethyl bromide, benzyl chloride and propyl bromide are suitable halides. Bromobenzene or chlorobenzene does not undergo this substitution because the $\mathrm{C}-\mathrm{X}$ bond is strengthened by partial double bond character and the ring blocks backside attack, so aniline cannot be made.
