Ella is convicted of a crime, but instead of serving time in jail, her sentence...

The best answer is B. Probation. In the CFE Law section on criminal justice, probation is identified as one of the sanctions that a court may impose after a defendant has been found guilty of a crime. The facts in this question match probation because Ella has already been convicted, but instead of immediately serving jail time, she remains in the community under supervision and must maintain good behavior. That is the classic structure of probation: a convicted offender is allowed to remain in the community, subject to conditions and oversight, rather than being incarcerated.

The other options do not fit as well. A deferred prosecution agreement generally concerns prosecutors agreeing to suspend or avoid prosecution—often in the corporate context—if specified conditions are met, so it applies before final conviction and is not the same as post-conviction community supervision. A determinate sentence refers to a fixed term of incarceration, while an indeterminate sentence involves a range rather than a fixed duration. Neither term specifically describes supervised release in the community in lieu of jail. Because Ella’s punishment is a suspended custodial consequence combined with supervision and a requirement of good conduct, probation is the most accurate choice.
