a1 only
b2 only
cBoth 1 and 2
dNeither 1 nor 2

ExplanationStatement 1 is correct : Tropical deserts indeed form along the western margins of continents within the trade wind belt due to several factors.Trade winds, blowing from east to west, lose moisture on eastern coasts and arrive dry on the western side.These regions lie under subtropical high-pressure belts (15°–30° latitude), where descending air suppresses cloud formation and rainfall.Additionally, cold ocean currents, such as the Hum- boldt Current, cool the air, reducing its moisture-holding capac- ity and creating stable, dry conditions.In some cases, mountains block moist winds, causing a rain shadow effect.Together, these factors create arid environments like the Sahara, Atacama, and Namib deserts.Statement 2 is incorrect : In India, the Eastern Himalayas expe- rience significantly higher rainfall compared to the Western Hi- malayas.This precipitation is primarily attributed to the South- west monsoon, rather than the Northeast monsoon.The Bay of Bengal branch of the monsoon carries moisture-laden winds that are funneled toward the Eastern Himalayas.When these winds enc
