The masses of 4He, 6Li, and 10B are 4.0015, 6.0135, and 10.0102 amu respectively. The fission of a boron-10 nucleus into He-4 and Li-6 would ?
1)need more info
2)absorb energy
3)evolve energy
4)result in no energy change?

See how the masses add up; i.e., is B-10 greater than the combined masses of H-4 and Li-6
so there is no energy change?
If there is a difference in mass, yes, there is an energy change. If not, no, there is no energy change.
