Assertion: Lower value of binding energy per nucleon indicates greater stability.
Reason : Binding energy per nucleon of `._(3)Li^(7)` is greater than that of `._(2)He^(4)`. Hence `._(3)Li^(7)` is less stable than `._(2)He^(4)`.

Options

A. If both, Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both, Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

D

Explanation

Assertion and the Reason, both are false. Lower value of binding energy per nucleon indicates lesser stability. Binding energy per nucleon of `._(3)Li^(7)` is lesser than that of `._(2)He^(4) :. ._(3)Li^(7)` is less stable then `._(2)He^(4)`
