Which one of the following receives an average annual rainfall of below 50 cm in India, indicating highest inadequacy?

Among the options, Ladakh — lying in the cold desert region of the trans-Himalayas (rain-shadow of the Greater Himalayas) — receives the lowest annual rainfall, typically less than 10 cm, far below the 50 cm threshold. This indicates the highest inadequacy of rainfall. Madhya Pradesh and Jharkhand receive moderate to high rainfall (100 cm or more in most parts), and Haryana receives around 50–75 cm. Hence Ladakh is the correct answer.
