Solution

The correct option is B $α - p a r t i c l e$
The binding energy per nucleon is the average energy required to remove one nucleon from the nucleus.

Thus, the one, which has the more binding energy per nucleon, will be more stable nuclei.

So, $α - particle$ is more stable compared to deuteron.

Hence, option $(B)$ is correct.
