The answer is; C

There are 2 Carbons, 4 Hydrogens, and 6 oxygens on both sides

All the moles of the elements on the right of the reaction equation are balanced with those on the left of the equation. These moles are indicated by the number in front of the symbols of the elements. This ensures that the first law of thermodynamics is observed. This law states that no matter or energy can be destroyed or created; It can only be transformed.
