NEET Physics Nuclear Fusion Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 12

Assertion (A): Nuclear fusion in stars requires extremely high temperatures. | Reason (R): High temperatures enable nuclei to overcome the Coulomb barrier by providing them with sufficient kinetic energy.

A

Both A and R are true, and R is the correct explanation of A.

B

Both A and R are true, but R is not the correct explanation of A.

C

A is true, but R is false.

D

A is false.
