Solution :(A) Aldol condensation, (in which CARBANION (nucleophile) gives nucleophilic addition and last STEP is dehydration). (B) G.R. attacks on CARBONYL group, followed by internal nucleophilic SUBSITITUTION
(C) `H_(2)SO_(4)` protonates OH group and changes it into good lenving group to give electrophilic carbon which under goes `ArSE_2` intermolecular reaction for ring CLOSURE.
(D) Intra molecular aldol condensation involves carbanion, nucleophilic addition and dehydration.
