Salicylic acid is warmed with ethanoic anhydride in the presence of a few drops of conc. . The product (aspirin) is

  1. Amethyl 2-hydroxybenzoate
  2. B2-acetoxybenzoic acid
  3. C2-hydroxybenzoyl chloride
  4. D2-hydroxyacetophenone

The phenolic OH is acetylated by the anhydride, giving 2-acetoxybenzoic acid (acetylsalicylic acid). The carboxylic acid group is untouched. Methyl salicylate would need methanol.
