An organic compound (A) of the molecular formula ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_3$ gives a positive Iodoform test but does not reduce Tollen's reagent. When (A) is subjected to acid-catalyzed hydrolysis, another compound B is formed which gives positive Tollen's test. Identify the unknown compound (A).
