The amount of water vapor that air can hold increases with temperature. Therefore, warmer air can hold more moisture than colder air. Since the parcel of air at 20°F has a higher temperature than the parcel at 0°F, it can hold more water vapor. According to the Clausius-Clapeyron equation, the saturation vapor pressure (SVP) of water vapor in air increases exponentially with temperature. The SVP at 20°F is roughly 5 times higher than the SVP at 0°F, which means the air at 20°F can contain roughly 5 times more water vapor than at 0°F. So, the answer is A, 5; more.
