Assertion: Hardy Weinberg's law is applicable only based on certain assumptions.
Reason: The law can be considered if nature acts as a selective force.
Codes:

(c) A is correct R is false
(d) Both A & B are false

Assertion: Mutations produced every generation will accumulate over generations to produce a new species.
Reason: Sudden and large variations cannot produce heritable changes.
