The climate on the leeward side of a mountain differs from that on the windward side mostly in the amount of rainfall. So the correct option is option "d" in regards to the question that has been given. The climatic condition of the windward side of the mountain is always like an ocean climatic condition while the leeward side has a very dry climate. The air on the windward side rises and gets cold and thus forms precipitation. On the other hand the air comes down on the leeward side and becomes warm and results in a drier climatic condition.
