Correct Answer - c
The mass of a nucleus is always less than the sum of the masses of the nucleons present in it. When nucleons combine to form a nucleus , some energy is liberated , and this is the binding energy of the nucleus . The mass of the nucleus cannot be more than the total mass of the nucleons because then stable nucleus cannot be formed .
