Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): In gymnosperms, the pollen grains are released from the microsporangium and carried by air currents.
Reason (R): Air currents carry the pollen grains to the mouth of the archegonia where the male gametes are discharged and pollen tube is not formed.
In the light of the above statements, choose the correct answer from the options given below:
1. (A) is False, (R) is True.
2. Both (A) and (R) are True and (R) correctly explains (A).
3. Both (A) and (R) are True and (R) does not correctly explain (A).
4. (A) is True, (R) is False.
