Assume that the nuclear binding energy per nucleon `(B//A)` versus mass number `(A)` is as shown in figure. Use this plot to choose the correct choice(s) given below.
(a) Fusion of two nuclei with mass numbers, lying in the range of `1ltAlt50` will release energy.
(b) Fusion of two nuclei with mass numbers lying in the range of `51ltAlt100` will release energy.
(c) Fission of a nucleus lying in the mass range of `100ltAlt200` will release energy when broken into two equal fragements.
(d) Fission of a nucleus lying in the mass range of `200ltAlt260` will release energy when broken into two equal fragments.

Options

A. `(i),(ii)`
B. `(ii),(iii)`
C. `(iii),(iv)`
D. `(ii),(iv)`

Answer

D

Explanation

In `(ii),(iv),B.E`./nucleon increses, enegry is released.
