2 answers:
Answer : A. It decreases and then increases.
Explanation : Troposphere is the lowermost layer of atmosphere.
Stratosphere is next layer up to the troposphere. As the jet descends from stratosphere towards the troposphere, the temperature initially decreases and then at troposphere is roughly constant and then steadily increases.
So, option (A) is correct.
