    Which of the following about the reaction given above is/are correct?

    1. Carbon is oxidized.

    2. Hydrogen is oxidized.

    3. Hydrogen is reduced.

    4. Carbon is reduced.

    1 only

    Incorrect Answer

    1 and 2 only

    Correct Answer

    2 and 3 only

    Incorrect Answer

    2 and 4 only

    Incorrect Answer
    Explanation:

    Oxidation: Gain of oxygen or loss of hydrogen; Loss of electrons or increase in oxidation state

    Reduction: Gain of hydrogen or loss of oxygen; Gain of electrons or decrease in oxidation state

    In the combustion of methane, carbon loses hydrogen and gains oxygen, so it is being oxidized. Oxygen gains hydrogen (and carbon), so it is being reduced.  Hydrogen gains oxygen (and loses carbon), so it is being oxidized.

    The correct option is B.
