The difference between the moist and dry adiabatic rates is due to:

The difference between the moist and dry adiabatic rates is due to:
  a. the fact that saturated air is always unstable.
  b. the fact that an unsaturated air parcel expands more rapidly than a saturated air parcel.
  c. the fact that moist air weighs less than dry air.
  d. the fact that latent heat is released by a rising parcel of saturated air
