    Answer:

    C

    Explanation:

    Assuming you had a few typos in the equations, I would say C

    I am going to assume the reaction

    _C2H6 + _O2 → _CO2 + _H2O

    Right now, there is enough hydrogen to make 3 water molecules, but since oxygen comes in groups of 2, it wouldn’t work.

    Therefore, we need 2 ethane molecules.

    2C2H6 + _O2 → _CO2 + _H2O

    Then balance the right side with the carbons and hydrogens

    2C2H6 + _O2 → 4CO2 + 6H2O

    So we need 4 O2’s in carbon dioxide and 3 O2’s in water (Since water uses 1 oxygen molecule per 2 hydrogens). Hence we will need 7 oxygens

    2C2H6 + 7O2 → 4CO2 + 6H2O

    And assuming errors in the typing, C should be the answer (if this matches)
