c upper troposphere
d thermosphere

Explanation:

Jet streams are fast - flowing, narrow air currents. They are located in the upper troposphere. The lower troposphere has more weather - related phenomena like convection currents for weather systems. The stratosphere has a more stable temperature profile with the ozone layer. The thermosphere is the upper - most layer of the atmosphere with very low density of air and high - energy processes.

C. Upper troposphere
