Assertion: Density of all the nuclei is same.

Reason: Radius of nucleus is directly proportional to the cube root ofmass number.

View answer and explanation

Correct option: B

Both Assertion and Reason are true and Reason is not the correct explanation of Assertion.

Option B (Both Assertion and Reason are true and Reason is not the correct explanation of Assertion) is correct because both statements are factually correct, but the constant density doesn't directly arise from the radius formula.
