From the binding energy per nucleon versus mass number curve:

(A) B.E/nucleon is small for light nuclei like ${}_1^1H, {}_1^2H, {}_1^3H$
(B) B.E/nucleon decreases in heavy nuclei making them less stable stab.
(C) When two light nuclei combine to form heavy nucleus, energy is absorbed.
(D) Heavy nucleus splits into lighter nuclei which results in liberation of energy.
