a. decreases
If a parcel of air rises, the temp decreases. If dry, a parcel with decrease at the dry adiabatic lapse rate of 9.8 C degrees per kilometer. The decrease in temperature is due to the expansion of the air as it rises.
If the parcel cools enough for water to begin to condense, it will still decrease in temperature as it rises. However, it will cool at a lower rate, typically around 5.5 degrees C per kilometer.
The inversion mentioned above only applies to the environmental lapse rate. This is the temperature change of the ambient air with height. It does not relate to rising/sinking air parcels, but rather the air that surrounds these parcels that can be assumed to be stationary. When an air parcel rises, the temperature of the air parcel decreases.

definitely d
Usually temp falls
If it rises and it can, this is called an inversion
