Answer:
B
Explanation:
Storms are formed when the movement of cold and warm air currents creates extreme air pressure difference.
The condition that cause storms to arise is the sudden change in the air pressure.
Air pressure should be impacted by the air molecules' weight. Also, the small air molecules contain some kind of weight and more air molecules that are made up of the atmosphere layers.
In the case when the storms should be created at the time of moving of cold and warm air so the current should develop the difference of extreme air pressure.
Therefore, the first option is correct.
