Match List I with List II and select the correct answer using the code given below the Lists List I (Climate type in letter code) A. Aw B. Af C. Cs D. Am List II (Major area) 1. Central California 2. Indian Sub-Continent 3. North and South of Amazon Forests 4. Western Equatorial Africa Codes A B C D

The Köppen climate classification system maps specific letter codes to distinct geographical regions. 'Aw' represents the Tropical Wet and Dry (Savanna) climate, which is extensively found north and south of the Amazon forest in Brazil [3]. 'Af' denotes the Tropical Rainforest climate, characterized by no dry season and found in Western Equatorial Africa, including the Congo basin [3]. 'Cs' refers to the Mediterranean climate, defined by dry summers and wet winters, which is a hallmark of Central California [2]. Finally, 'Am' signifies the Tropical Monsoon climate, which is the dominant climatic type of the Indian Sub-continent due to seasonal wind reversals [2]. Matching these pairs (A-3, B-4, C-1, D-2) leads to the correct sequence 3, 4, 1, 2, which corresponds to Option 3.
