    A. Lose 4 electrons

    Explanation:

    The reaction equation is given as:

    S + NO₃ → SO₂ + NO

    The half equation of the reaction for S:

    S → SO₂

    For S to go into SO₂,

    we move from an oxidation state of 0 to + 4,

    Finding the oxidation state of S in SO₂

    a + (-2 x 2) = 0

    a - 4 = 0

    a = 4

    This is a loss of 4 electrons
