Your answer: —  ·  Correct: C
Explanation

According to Köppen's climatic classification, the western fringe of Rajasthan, which encompasses the Thar Desert, is categorized as BWhw. The code 'B' represents dry climates, 'W' signifies arid desert conditions, and 'h' indicates hot temperatures where the mean annual temperature is above 18°C [4]. The small 'w' denotes a dry winter season. This region is characterized by extreme aridity, very low rainfall, and high evaporation rates [2]. In contrast, 'Amw' refers to tropical monsoon climates found on the Malabar Coast, 'Aw' describes tropical savanna climates prevalent in Peninsular India, and 'Cwg' represents the humid subtropical climate with dry winters typical of the Indo-Gangetic Plain [1]. Therefore, BWhw is the most accurate description for the hot desert environment of western Rajasthan.
