पृथ्वी के वायुमंडल के भीतर तापीय ऊर्जा का महत्वपूर्ण संवहनी स्थानांतरण (Convective transfer) और ऊर्ध्वाधर मिश्रण मुख्य रूप से कहाँ तक सीमित रहता है?

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: The magnitude of the moist adiabatic lapse rate is always less than that of the dry adiabatic lapse rate. Reason R: The rate of change of the saturation vapor pressure with temperature is always negative. In the light of the above statements, choose the most appropriate answer from the options given below:

If an air parcel cools at a constant pressure through the evaporation of water into it until it reaches saturation, the temperature attained is known as the:
