Answer 2

Answer:

b) is very stable

versus mass number plot are very tightly bound and hence, are stable. And the elements those are lower on this plot, are less tightly bound, are unstable. Since the helium nucleus shows a peak on this plot so, it is very stable

Hope it will help you and sorry if it is wrong and have good time mate.
