When Viewed in the Infrared Light Emitted by the Clouds

When viewed in the infrared light emitted by the clouds, the brightest parts of Jupiter are:

A) in the belts, which correspond to deeper and hotter regions.
B) directly along the equator, where sunlight is most direct and effective in heating the gas.
C) in the zones, corresponding as expected to brighter regions in visible light.
D) over the north and south magnetic poles, where magnetospheric interaction heats the atmosphere.
