D Correct answer
Explanation

Most weather phenomena occur in the troposphere, the lowest atmospheric layer extending up to 10-15 km. This layer contains 75% of the atmosphere's mass and nearly all water vapor. The stratosphere (ozone layer), exosphere (outermost), and ionosphere (charged particles) have minimal weather activity.
