A Correct answer
Explanation

In a stable atmosphere, the Environmental Lapse Rate is less than the Dry Adiabatic Lapse Rate. When a parcel is pushed upward, it becomes cooler and denser than surrounding air, causing it to sink back to its original position. This stability suppresses vertical air motion.
