Text Solution

Verified by Experts
The correct answer is:
C

The binding energy per nucleon for the middle nuclides (from to ) is maximum. Hence, these are more stable.
As the mass number increases, the binding energy per nucleon gradually decreases and ultimately binding energy per nucleon of heavy nuclides (such as uranium etc.) is comparatively low. Hence, these nuclides are relatively unstable. So, they can be fashioned easily.
