Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Assertion is true since i7 states the concept of radioactive isotopes.
$U_{A}$ and $U_{Z}$ display how nuclear isotopes lead to different radioactivity. So the reason explains the assertion. Thus option A is correct.
