The correct answer is A. Less liquid water would exist on its surface because it would be much warmer.

Explanation

The Earth's atmosphere is composed of several gases, including Carbon Dioxide, which in normal conditions should be 0.04% of the total of these gases. On the other hand, the atmosphere of the planet Venus has a 95% concentration of Carbon Dioxide. Therefore, if the Earth had the same amount of Carbon Dioxide as the planet Venus, it would have a much higher temperature, which would cause the liquid water available on the surface to decrease considerably because a large amount of carbon dioxide would evaporate. the same. So the correct answer is A. Less liquid water would exist on its surface because it would be much warmer.
