Low density
AnswerC.
Low viscosity

Solution
Answer: Option B
Solution:
The key to why clouds float is that the density of the same volume of cloud material is less than the density of the same amount of dry air. Just as oil floats on water because it is less dense, clouds float on air because the moist air in clouds is less dense than dry air.
