Match List-I with List-II and select the correct answer using the code given below the lists:

List-I (Köppen's Climatic type)	List-II (Letter Code)
A. Tropical wet	1. Af
B. Mid-latitude desert	2. Cs
C. Mediterranean	3. Df
D. Humid continental	4. BWk

Code:

• (A) 1 4 2 3
• (B) 1 2 4 3
• (C) 3 2 4 1
• (D) 3 4 2 1

The Köppen climate classification system uses letter codes to categorize global climates. Tropical wet (Tropical Rainforest) is represented by 'Af', where 'A' denotes tropical and 'f' indicates no dry season [2]. Mid-latitude desert (Cold Desert) is coded as 'BWk', where 'BW' signifies arid desert and 'k' (kalt) denotes cold mid-latitude temperatures [3]. Mediterranean climate is designated as 'Cs', characterized by warm temperate conditions ('C') and dry summers ('s') [4]. Humid continental climate falls under the 'D' group (Cold Snow-Forest) and is represented by 'Df', indicating a moist continental climate with no dry season [5]. Matching these pairs (A-1, B-4, C-2, D-3) leads to the code 1-4-2-3, which corresponds to the first option.
