Which statement best explains why an increase in the relative humidity of a parcel of air generally increases the chance of precipitation?

• The dew point is farther from the condensation point, causing rain.

• The air temperature is closer to the dew point, making cloud formation more likely.

• The amount of moisture in the air is greater, making the air heavier.

• The specific heat of the moist air is greater than the drier air, releasing energy.
