What question was investigated based on the data graphed here?

a. what part of earth has the most global radiation over the year?

b. does radiated heat affect conditions found in outer space?

c. does the amount of cloud cover affect the temperature on earth?

d. does the amount of radiation from the sun affect air temperature?

The correct option is D) Does the amount of radiation from the sun affect air temperature?

Explanation:

The graph represents the effect of Sunlight or global radiation on the temperature of the air present in the atmosphere.

As we know, as the amount of radiation increases, the temperature of the Earth also increases. This phenomenon is perfectly illustrated in the graph mentioned in the question. Hence, D is the correct option.

Other options like option A are not correct because the graph does not illustrates the parts of the Earth which receive the most global radiation over a year.
