- I and IV
-
II and III
- II and IV
The correct answer is: C
Explanation
Rainfall and relative humidity have a positive relationship, meaning that rainfall increases relative humidity, and relative humidity increases rainfall. Rainwater evaporates into the air, increasing the amount of water vapour in the air. The longer it rains, the more water vapour is added to the air. Consequently, an increase in rainfall only implies the increase emanated from increased relative humidity. Since the ecological zones with high rainfall of 2000 and 2200 are II and III respectively. Option C is the correct answer.
