Explanations:The development of a low-pressure area in Rajasthan towards the end of May is a significant meteorological phenomenon that influences the weather patterns and the onset of the monsoon season in the region. This low-pressure area is elongated and extends from the Thar Desert in the northwest to Patna and Chotanagpur in the east and southeast.
The Thar Desert, also known as the Great Indian Desert, is located in the northwestern part of India, primarily in Rajasthan. It is characterized by its arid and semi-arid climate, with very low rainfall and high temperatures. The Chotanagpur Plateau, on the other hand, is located in the eastern part of India, covering parts of Jharkhand, Chhattisgarh, and West Bengal. Patna is a major city in the state of Bihar, situated in the eastern part of India.
The low-pressure area that develops in May is a result of the heating of the landmass, which causes the air to rise and create a region of low pressure. This low-pressure system is crucial for the monsoon season, as it helps to draw in moisture-laden winds from the Bay of Bengal and the Arabian Sea, leading to the onset of the monsoon rains in the region.
Understanding the geographical distribution of this low-pressure area is important for predicting weather patterns and preparing for the monsoon season. The correct answer, Option C, accurately reflects the extension of the low-pressure area from the Thar Desert in the northwest to Patna and Chotanagpur in the east and southeast, which is consistent with the meteorological observations and geographical locations of these regions.
