The correct answer is Orographic rainfall. The rain shadow effect is a direct consequence of orographic lift and precipitation.

Orographic rainfall occurs when moist air is forced to rise over a mountain range. As the air rises, it cools, condenses, and precipitates on the windward side of the mountains. By the time the air descends on the leeward side, it has lost most of its moisture and warms up, creating a dry area known as a rain shadow.

Cyclonic rainfall is associated with low-pressure systems (cyclones). Convectional rainfall occurs due to intense heating of the ground, causing air to rise, cool, and condense. Frontal rainfall occurs where two different air masses meet along a front. Only orographic rainfall directly leads to the distinct wet windward side and dry leeward (rain shadow) side of a mountain range.
