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): | Biologists make a statistical comparison of the temperate-tropical species richness of an exhaustively studied group of insects and extrapolate this richness to other group of animals and plants and come up with a gross estimate of the total number of species on earth. |
| Reason (R): | Insects are the most successful living organisms among animals and plants. |
| 1. | Both (A) and (R) are True but (R) does not explain (A). |
| 2. | (A) is True but (R) is False. |
| 3. | (A) is False but (R) is True. |
| 4. | Both (A) and (R) are True and (R) explains (A). |
