Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): If hybrid seed are produced through apomixis then it is very useful for farmer.
Reason (R): If hybrid seed are produced through apomixis then there is no segregations of characters in the hybrid progeny then the farmers can keep on using the hybrid seeds to raise new crop year after year and he does not have to buy hybrid seeds every year.
In the light of the above statements, choose the correct answer from the options given below.
Both (A) and (R) are true but (R) is not the correct explanation of (A)
(A) is true but (R) is false
(A) is false but (R) is true
