    Valence shell is outermost shell of an atom.

    Atomic number of carbon is 6 and its electronic distribution is 2, 4.

    Atomic number of hydrogen is 1 and its electronic distribution is 1.

    Atomic number of magnesium is 12 and its electronic distribution is 2, 8, 2.

    Atomic number of oxygen is 8 and its electronic distribution is 2, 6.

    Therefore, each element is matched to the number of electrons in its valence shell as follows.

    1. Carbon (C) - D) Four.

    2. Hydrogen (H) - C) One.

    3. Magnesium (Mg) - A) Two.

    4. Oxygen (O) - B) Six.
