What can be the main climatic challenge for agriculture in a rain shadow region?

Answer and explanation

Correct answer: Low rainfall due to rain shadow

Answer: B. A rain-shadow region lies on the leeward side of a mountain range. Moist air rises on the windward side, cools, and loses much of its moisture through condensation and precipitation. After crossing the ridge, the descending air is generally drier and warmer, so the leeward side receives less rainfall. For agriculture, this can mean limited soil moisture, greater dependence on irrigation, and higher risk of water stress, although the actual impact varies with soils, seasons, and local water supply. A is wrong because the rain-shadow effect is associated with reduced, not daily heavy, rainfall. C is a coastal process and is not the principal climatic challenge here. D is wrong because high places do not lack air; the issue is dryness and limited precipitation. Memory cue: windward side is wetter, leeward side is drier—mountains can create an agricultural moisture contrast.
