B Correct answer
Explanation

The greenhouse effect maintains Earth's warm temperature by trapping heat in the atmosphere through greenhouse gases. Without this natural effect, Earth's average temperature would be about -18°C instead of the current +15°C. It does not primarily maintain water balance, the carbon cycle, or the ozone layer.
