the binding energy of deuteron 1 pow 2h is 115 mev per

The binding energy of deuteron $$\left( {_1^2H} \right)$$ is $$1.15\ MeV$$ per nucleon and an alpha particle $$\left( {_2^4He} \right)$$ has a binding energy of $$7.1\,MeV$$ per nucleon. Then in the reaction
$$_1^2H + _1^2H \to _2^2He + Q$$
the energy released $$Q$$ is :

A. $$5.95\,MeV$$

B. $$26.1\,MeV$$

C. $$23.8\,MeV$$

D. $$289.4\,MeV$$

Answer : $$23.8\,MeV$$

Solution :
Given, $$_1{H^2}{ + _1}{H^2}{ \to _2}{H^4} + Q$$
The total binding energy of the deutrons $$ = 4 \times 1.15 = 4.60\,MeV$$
The total binding energy of alpha particle $$ = 4 \times 7.1 = 28.4\,MeV$$
The energy released in the process $$ = 28.4 - 4.60 = 23.8\,MeV.$$
