When the temperature of a parcel of air becomes lower than the surrounding air the parcel's upward motion is a) inhibited b) enhanced c) improved d) accelerated

A) inhibited

Explanation:

When the temperature of the parcel of air becomes lower than the surrounding air the parcel upward motions are inhibited as, lowering the temperature means in the air parcel the density increased which means that there is decreased in the molecules and stop in the upward motion. But in the outer parcel the temperature are higher so that is why it is continue to increased in the parcel.
