Assume that the nuclear binding energy per nuclear (B/A) versus mass number (A) is as shown in the figure. Use this plot to choose the correct choice(s) given below:
1. Fusion of two nuclei with mass number lying in the range of 51<A<100 will release energy
2. Fusion of a nucleus lying in the mass range of 200<A<260 will release energy when broken into two equal fragments
3. Both A and B
4. None of these
