D Correct answer
Explanation

The stratosphere lies directly above the troposphere, extending from about 10-15 km altitude to roughly 50 km. This layer contains the ozone layer and is characterized by stable, stratified air with minimal vertical mixing. The troposphere (lowest layer) is where all weather occurs, and the stratosphere sits immediately above it.
