Answer & Solution

Answer: (Detailed Solution Below)

Option B: Both (A) and (R) are true, but (R) is not the correct explanation of (A

Detailed Solution:

The correct answer is “Both (A) and (R) are true, but (R) is not the correct explanation of (A”.
Natural vegetation is the true index of climate. This statement is true because the types of plants that grow in a particular region are influenced by the climate conditions, such as temperature, rainfall, and humidity.

Plants that require a lot of moisture, such as water lilies and mangroves, are typically found in areas with high rainfall or near water bodies.

Natural vegetation is influenced by many factors like temperature, precipitation, soil types, and other climatic conditions, not just the presence of water-loving plants in a moist climate.
