The correct answer is option 1, orographic rainfall.

Inversion of rainfall is a phenomenon that occurs when there is a change in the temperature of the atmosphere with height. In normal atmospheric conditions, the temperature decreases as you move higher in the atmosphere. However, in an inversion, the temperature actually increases with height, creating a layer of warmer air above a cooler layer.

When warm, moist air encounters a mountain range, it is forced to rise and cool. As it does so, the moisture in the air condenses, forming clouds and eventually rainfall. This process is known as orographic rainfall. The presence of an inversion can enhance this process, as the warmer layer of air above the mountain helps to trap and sustain the rising air, leading to increased rainfall.

Convectional rainfall, option 2, occurs when the sun heats the Earth`s surface, causing the air to rise and form clouds. Cyclonic rainfall, both tropical and temperate, option 3 and 4 respectively, is associated with the movement of cyclones (low-pressure systems) that bring large amounts of rainfall. These types of rainfall are not specifically related to the phenomenon of inversion.
