Explanation / Answer

Second rxn has fastest rate.

Because here OH- ion work as nucleophile.and reaction complete from SN1 mechanism then rate determining step is the step of formation of cation ion.

And 2nd compound has more stable cation ion (because here + ion is in resonance) so nucelophile attack that compound faster which has more stable cation compound there.

So answer is 2.
