This is a short answer type question as classified in NCERT Exemplar
Due to the resonance stabilisation of the benzyl ring, compound (B) would conduct the SN1 reaction faster than compound (A). The carbocation C6H5CH2Cl+ is very stable when the -Cl from the ring is cleaved, and it is driven to carry out the SN1 reaction.
