AIIMS 2018 Botany Camouflage Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 12

Assertion: Animals adopt different strategies to survive in hostile environment. Reason: Praying mantis is green in colour which merges with plant foliage.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Correct Answer

Option D

Detailed Explanation

Option D is correct because while the assertion about animals adopting different survival strategies in hostile environments is true, the reason provided is misleading. The praying mantis is not exclusively green; it can also be brown or other colors depending on its habitat, and its coloration does not solely serve to merge with foliage but also helps in ambush predation. Other options are incorrect because option A suggests the reason explains the assertion, which it does not; option B claims both are true but fails to connect them correctly; and option C incorrectly states the reason is false when it is simply not applicable in this context. Understanding the adaptive strategies of animals, including camouflage, highlights the complexity of ecological interactions and survival mechanisms.
