Explanation:

Radiative Forcing is the measurement of capacity of any gas to delay the escape of heat in the energy budge of the earth. It is measured in watt/m2. Positive radiative forcing increase earth’s heat budget whereas negative radiative forcing decrease earth’s heath budget. Hence, statements 2 and 3 are incorrect and the correct statement is 1 only. Therefore, answer is A.
