• A. 1 only

Answer 1

The correct option is C 3 only

Explanation:

Statement 1 is incorrect: Water vapour is the most potent greenhouse gas in the earth’s atmosphere.

Statement 2 is incorrect: Water vapour’s primary role is not a direct agent of radiative forcing but rather as a climate feedback. As water vapour in the atmosphere increases with increase in the temperature.

Statement 3 is correct: Methane is more potent than Carbon dioxide because the radiative forcing produced per molecule is greater than Carbon dioxide.
