If condensation nuclei are abundant but water vapour is low, why can rainfall formation remain limited?
Answer and explanation
Correct answer: Because sufficient moisture is also necessary for rainfall
The governing concept is cloud microphysics: condensation nuclei are surfaces on which water vapour can condense, but they do not supply the water themselves. When humidity is low, only limited vapour is available to form droplets, and droplets may remain too small to grow into raindrops. Therefore A is correct. B wrongly treats nuclei as barriers, while C and D assign cloud formation to unrelated gases.
