Answer:
d) all of these choices.
Step-by-step explanation:
- expiration of their term.
This happens when the inmates has finished the total years of punishment required by the judge during the verdict.
- commutation of their sentence.
This happens when the total of inmate's punishment is reduced by the court due to good behaviors that the inmate showed during the prison time.
- court orders to relieve over-crowded prisons
This happens when the government do not have enough fund to take care more inmates so they let go a couple of old inmates to make rooms for the new one.
