Assertion : Nuclei having mass number about 60 are most stable. Reason : When two or more light nuclei are combined into a heavier nucleus, then the binding energy per nucleon will increase.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion

Step-by-step solution

The nuclei having mass number A 60 have maximum binding energy per nuclean (about 8.7 MeV). So, these nuclei are most stable.
