Given below are two statements. One is labelled as Assertion (A) and the other is labelled as reason (R). 

Assertion (A): Camouflage is a defense mechanism in frogs.

Reason (R): Concealing colour protects them from predators.

In the light of the given statements, choose the correct answer from the options given. 

The correct answer is (1) Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation:

Frogs are known to exhibit camouflage, which is a natural defense mechanism used by many animals to avoid being detected by predators. The color of the frog's skin can blend in with its surroundings, making it difficult for predators to spot them.

The reason for this is that concealing coloration protects frogs from predators. By blending in with their surroundings, they are less likely to be seen and attacked by predators. This is particularly important for frogs that are not particularly fast or agile and rely on camouflage to stay hidden.

Therefore, both assertion (A) and reason (R) are true, and (R) correctly explains why (A) is true.
