Answer

To determine the formula of glycolic acid from the given options, we need to recognize that glycolic acid is characterized by the presence of a hydroxyl group (-OH) and a carboxylic acid group (-COOH). The correct molecular formula for glycolic acid includes two carbon atoms, three hydrogen atoms, and two oxygen atoms. Thus, among the options presented, option A: HOCH2COOH represents glycolic acid accurately.
