Detailed Solution:

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

Tropical countries have a higher concentration of butterfly species due to their favorable climatic conditions.

Butterflies are cold-blooded creatures and require a constant supply of warmth to maintain their body temperature and carry out essential life functions. Tropical regions offer consistent warmth, abundance of food plants, and fewer extreme weather conditions, making them ideal habitats for butterflies.
