Which of the following statement is correct?
  1. The rest mass of the stable nucleus is less than the sum of the rest masses of its separated nucleons
  2. The rest mass of the stable nucleus is greater than the sum of the rest masses of its separated nucleons
  3. In nuclear fission, energy is released by fusion is of two nuclei of medium mass (approximate 100 amu)
  4. None of these
