Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
In the light of the above statements, choose the most appropriate answer from the options given below :
| Assertion (A): | Conventional breeding is not the answer if we want to increase yield in the existing crop varieties. |
| Reason (R): | The existing crop varieties have evolved into new species and traditional hybridisation is not possible now. |
| 1. | Both (A) and (R) are False. |
| 2. | Both (A) and (R) are True but (R) does not explain (A). |
| 3. | (A) is True but (R) is False. |
