Detailed explanation-1: -The state has two particular times of precipitation: precipitation because of the South-West Monsoon after summer and precipitation because of Western Disturbances. Rajasthan gets low and variable rainfalls and in this way is inclined to dry spells. Thus, option (D) is correct.
Detailed explanation-2: -Because of its geographical location, Rajasthan receives scanty rainfall. We know about the southwestern monsoon which is the main cause of rainfall in most parts of India.
Detailed explanation-3: -High air pressure during summers is not a reason for scanty rainfall in western Rajasthan.
Detailed explanation-4: -The Arabian Sea branch of the South west monsoon blows parallel to the Aravalli Hills. Since the moisture-bearing winds do not strike the mountains, they do not cause any precipitation in Western Rajasthan.
Detailed explanation-5: -The Bay of Bengal branch of the Indian monsoon loses its moisture by the time it reaches the north-western part of India where Rajasthan is located. And the Arabian sea branch of the monsoon flows parallel to the Aravalli Mountains and reach the northern part of India but does not shed moisture over Rajasthan.
