Correct Answer: Earth


Solution : The first option is correct.

EXPLANATION:

Earth's atmosphere contains about 0.04% carbon dioxide (as per last update in January 2022), which is less than 1% of the atmosphere, while the majority is composed of nitrogen (about 78%) and oxygen (about 21%). So, here, we deduce that the presence of carbon dioxide in the atmosphere is less than 4%, and also in the paragraph, there is a comparison between Venus and Earth only.

Therefore, the right answer is Earth .
