Strategy:
 Determine the empirical formula of the substance using the weight of Hydrogen, Oxygen, and Carbon produced. Matches occur if the compound's ratio of Carbon to Hydrogen to Oxygen is .

Step 1: Calculate mole ratios
- Carbon: 
- Hydrogen: 
- Oxygen: 
Simplest ratio: .
This points to an empirical formula of .

Step 2: Check matching compounds
- (A) Acetic acid (): Formula , ratio . Matches.
- (B) Formaldehyde (): Formula , ratio . Matches.
- (C) Dimethyl peroxide / similar: Ratio differs
