Relative humidity
B.

All of the above
Answer: Option B
Solution
Answer: Option B
Solution:
The air parcel expands as it rises and this expansion, or work, causes the temperature of the air parcel to decrease. As the parcel rises, its humidity increases until it reaches 100%. When this occurs, cloud droplets begin forming as the excess water vapour condenses on the largest aerosol particles.
