Hint: Temperature reversal happens when the natural temperature gradient is reversed. Air is trapped under warm air when the temperature reversal reverses and the pocket of staggered air at the surface of the planet is producing a pocket of stagnating air.

Complete answer: When a layer of warm air is raised over a layer of cooler air just above the ground, a thermal inversion occurs. The cold air is held warm and contaminants are not emanating and dispersed. These are critical for meteorology, as they block the atmospheric flow, which makes air-stable over a region with an inversion. Different weather patterns can then be accomplished. More significantly, however, areas with extreme emissions are vulnerable to harmful air and increased smog if an inversion happens because contaminants are trapped in the soil instead of being extracted. The air temperature usually falls at a rate of \[3.5{}^\circ F\] every 1000 feet (or approximately \[6.4{}^\circ C\] per kilometre) you reach the atmosphere. When this cycle is present, the air flows continuously between warm and cold regions. When it's an unstable air mass. The air will better blend and disseminate around contaminants. Temperatures increase with rising altitude during an inversion episode. The warm reverse layer serves as a cap, preventing mixing in the atmosphere. Therefore, invert layers are referred to as stable air masses.
Hence, option B-Cool ground air gets overlapped by warm air is the correct answer.

Note: The severe weather conditions they can often produce are some of the most critical consequences of the temperature reversal. The freezing rain is one example. This is because the snow melts when it passes through the warm inverse stage as it forms with temperature inversions in a cold environment. The precipitation then goes through the cold air layer close to the ground.
