Answer:
Hadley.
Explanation:
In 1735, George Hadley proposed a model of the atmospheric circulation for planet Earth and it was referred to as the Hadley cell.
Hadley cell are low-latitude overturning circulations which comprises warm, moist air that rises into the atmosphere near the equator and air sinking at roughly 30 degrees latitude.
This ultimately implies that, the Hadley cell is the continuous atmospheric convection cell in the Northern and Southern Hemisphere which have an ascending limb near the equator and a descending limb near 30 degrees latitude.
Additionally, the south-moving winds and north-moving winds connect the columns of vertical movement at low altitudes and high altitudes respectively.
The correct answer is the third option: "A nation that has made major social, political, and economic progress."

Also called development economic zone or special economic zone.
Formula for speed of light is:

Where:
c=speed of light = 300000 km/s
d=distance
t =time
Rearranging formula for t and calculating:
The size of the body of water , usually an ocean is bigger than a sea.
