Thunderstorms are short-lived violent weather, which is associated with extreme lightning, dense clouds, heavy rain, and gusty winds. The lifting force, moisture in the middle layers, and rising air are the causes of thunderstorms.
The correct option is:
Option A. A stationary front.
The thunderstorm is caused due to:
1. The rising air is needed to form clouds and thunderstorms. This rising air needs a buoyant force to move the air upside. Moistures produced from the oceans and seas lead to instability, which causes a difference in the air density.
2. The stationary front is known to produce severe weather. The weather is often cloudy and the difference in the air temperatures leads to the formation of a stationary front.
Thus, the stationary front is not involved in the thunderstorm.
