Question

Assertion : The megaspore mother cell undergoes mitosis to Produce four megaspores.

Reason : Megaspore mother cells and the megaspores are both haploid.

(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 correct explanation of A

(c) A is true but R is false

(d) A and R are false
