Which natural feature in the northwest India marks the beginning of the low-pressure trough during the summer months?

​The correct answer is: (C) Thar Desert
​Explanation:
● During summer, intense heating over the Thar Desert creates a strong low-pressure area.
● This low pressure forms the starting point of the summer trough extending eastward.
● It plays a key role in drawing in southwest monsoon winds.
​Information Booster:
● Thar Desert heats faster than surrounding regions.
● The trough extends from Thar to the Ganga plains.
● Helps pull moisture-laden winds from the Arabian Sea.
● Strengthens monsoon circulation.
● Peak formation occurs in May–June.
​Additional Knowledge:

● Satpura Range: Located in central India, mainly across Madhya Pradesh, Maharashtra, and Chhattisgarh.
● Aravalli Hills: Stretch from Gujarat through Rajasthan to Delhi–Haryana in a southwest–northeast direction.
