What is the answer to this question?

An organic acid contains C, H, and o. In one combustion analysis, 5.24 g of acid yields 7.86 g CO2 and 2.14 g H2O. Calculate the empirical formula and molecular formula of acid given that its molar mass is about 176 g/mol. A Empirical formula C.H. : molecular formula - C H2002 B Empirical formula - C,H,O, ; molecular formula - CH. Empirical formula - CH ; molecular formula - C H2004 10 D Empirical formula - CH20 ; molecular formula - C4182
