Explanation:

- Parole (Option 2) : This is the early release of a prisoner who must then follow specific conditions and is supervised in the community.

- Active Supervision (Option 1): This means regular monitoring of an offender in the community but isn't necessarily tied to early prison release.

- Split Sentence (Option 3): This is when an offender serves part of the sentence in prison and the rest in the community, but not exactly “early release.”

- Inactive Supervision (Option 4): This is minimal or no active monitoring of an offender in the community.
