    Option (d) is correct. 800 calories of heat is released.

    Explanation:

    The formula for the heat is given by

    Q = m L

    Q = heat energy

    m = mass = 10 g

    L = latent heat of fusion=80 cal/gram

    so Heat energy = Q = 10 (80) = 800 cal

    the heat energy is released.

    so 800 calories of heat is released.
