Explanation: Rajasthan, a state in northwestern India, is known for its arid and semi-arid climate, which is characterized by very little rainfall. The state is part of the Thar Desert, one of the largest deserts in the world, and is known for its hot and dry conditions. The average annual rainfall in Rajasthan is around 200-300 mm, which is significantly lower than the national average. This low rainfall is due to the state's geographical location and the influence of the monsoon winds, which do not reach the region as effectively as they do the eastern and southern parts of India.
Gujarat, another state in western India, shares some climatic similarities with Rajasthan, especially in its western and central regions. However, the eastern and coastal parts of Gujarat receive more rainfall due to the influence of the Arabian Sea. Despite this, the overall rainfall in Gujarat is still relatively low compared to other parts of India.
In contrast, the other statements in the question are accurate based on the typical weather patterns in India. Kerala and Karnataka, located in the Western Ghats region, receive pre-monsoon showers due to the influence of the Arabian Sea. These showers are a common occurrence before the onset of the monsoon season, contributing to the lush greenery of these regions. In October, as the monsoon season wanes, the weather in many parts of India, including Rajasthan, can become oppressive during the day due to the high temperatures and humidity. This is a typical weather pattern as the region transitions from the monsoon to the post-monsoon season. The deltas of the Godavari and Krishna rivers are located in coastal regions that are frequently struck by cyclones, especially during the monsoon and post-monsoon seasons. These cyclones can cause significant damage due to the high population density and low-lying nature of these areas.
Therefore, the incorrect statement is Option A, as Rajasthan and parts of Gujarat do not receive abundant rainfall. The misconception here is that these regions are often associated with dry and hot conditions rather than abundant rainfall, which is a common misunderstanding about the climatic conditions of these regions.
