Q. No.Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A):

Reason (R):
Insects are the most successful living organisms among animals and plants.
In the light of the above statements, choose the most appropriate answer from the options given below :
1.
Both (A) and (R) are True but (R) does not explain (A).
