Correct Answer: Option (C) — Both 1 and 2

Concept & Option Breakdown

Standard Reference Verified

Statement 1 is correct: The Southwest Monsoon arrives earliest in southern India (around late May/early June) and retreats latest (October/November), giving it a longer duration. In northern India, it arrives later (late June/early July) and withdraws earlier (September), resulting in a shorter monsoon duration.

Statement 2 is correct: In the Indo-Gangetic Plains, the Bay of Bengal branch of the monsoon moves westward, shedding moisture progressively; hence rainfall decreases from east (e.g., Kolkata: ~120 cm) to west (e.g., Delhi: ~56 cm; western Rajasthan: <20 cm).

Elimination Heuristic & Exam Approach

Monsoon winds enter from south/east and lose moisture as they penetrate deeper inland toward the northwest, making both statements fully consistent with basic monsoon dynamics.
