Detailed Solution

(A) is true but (R) is false.

Explanation:

(A) is true because different groups of animals have evolved different mechanisms of breathing based on their adaptations to their respective environments. For example, fish extract oxygen from water using gills, while mammals inhale air into lungs to extract oxygen.

(R) is false because the mechanism of breathing depends mainly on the animal's habits as well as habitats. For example, aquatic organisms respire through gills in general.
