Answer 1

The correct response is:

Venus's atmosphere has a higher proportion of carbon dioxide than Earth's, so greenhouse gasses trap more heat.

Venus has about 96.5% carbon dioxide in its atmosphere, compared to Earth's roughly 0.04%. This significantly higher concentration of greenhouse gases on Venus leads to an intense greenhouse effect, resulting in much higher surface temperatures.
