Solution

The correct option is A The blinding energy of helium nucleus
Binding energy, by definition, is the amount of work you need to do to separate nucleons bound in a nucleus to infinity. Since (for most nuclei), you need to supply energy to free the nucleons, the opposite process will release energy - bringing nucleons together to form a nucleus will release energy.
