Answer: A, B, D
The carboxylic acid group of salicylic acid is acidic enough to release COX2 from bicarbonate, and the phenolic OH gives the violet iron complex and is acetylated by ethanoic anhydride to give aspirin. With bromine water, the strongly activated ring is brominated and the carboxyl group is lost, giving 2,4,6-tribromophenol, so the last statement is wrong.
