A Correct answer
Explanation

The troposphere is the lowest layer of Earth's atmosphere, extending from the surface to about 10-15 km altitude. This layer contains approximately 75% of the atmosphere's mass and virtually all weather phenomena including clouds, rain, storms, and temperature variations. The stratosphere above it contains the ozone layer but has minimal weather activity.
