The FTIR spectrum indicates the presence of hydroxyl (broad peak at 3400 cm-1) and carbonyl (strong peak at 1720 cm-1) functional groups, suggesting a carboxylic acid or ester. The 1H NMR spectrum shows aromatic hydrogens, indicating the presence of a benzene ring. The mass spectrum fragment at m/z = 77 corresponds to a common fragment for aromatic compounds. Given these clues, the correct formula is C7H6O2, which aligns with the presence of both the hydroxyl and carbonyl groups."}
