Assertion: In the process of nuclear fis...

Assertion: In the process of nuclear fission, the fragments emit two or three neutrons as soon as they are formed and subsequently emit particles.
Reason : As the fragments contain an excess of neutrons over protons, emission of neutrons and particles bring their neutron/proton ratio the to stable values

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.
