Global atmospheric circulation tends to produce arid areas at:

Correct option is A

Explanation:
Arid regions or deserts are commonly found near 30° north and south latitude due to the descending limbs of the Hadley cells. In these zones, dry air descends, warms up, and inhibits cloud formation and precipitation, resulting in dry desert climates.
Information Booster:
The Hadley Cell circulation is responsible for transporting warm air from the equator towards higher latitudes. This air rises at the equator due to intense solar heating, moves poleward, and then descends around 30° latitude:
· Descending air is dry, creating high-pressure zones.
· These zones are associated with clear skies and low rainfall, forming deserts like the Sahara, Arabian, and Australian deserts.
Additional Knowledge:
· Option (2): 10° Latitude – Near the Intertropical Convergence Zone (ITCZ), which is humid and experiences high rainfall.
· Option (3): 60° Latitude – Associated with low-pressure zones and precipitation, not aridity.
· Option (4): Equator – Experiences high rainfall and humidity due to rising warm air and convection.
