Solution

The correct option is A $_{1} H^{2}$
The binding energy is the energy that is required to break the nucleons apart. The curve of Binding energy per nucleon Vs the Mass number shows the highest binding energy is that of Iron no other is tightly bound. Except the light nuclei having BE. $56 M e V$ .

Hence the most stable nucleon is $2 .22 M e V$
