• C. It would be higher than the present.
• D. It depends on the $0_2$ content of air.

Answer 1

The correct option is A It would, be less than the present.

When carbon dioxide and other air pollutants are collected in the atmosphere they absorb sunlight that has bounced from the earth’s surface. This leads to an increase in the earth's average surface temperature and is called global warming. When there is no carbon dioxide in the atmosphere, the temperature of the Earth's surface will be less than the present temperature.

Thus, the correct answer is option A.
