Which term represents a sentence imposed by state law that does not give discretion on the duration?

The term that represents a sentence imposed by state law that does not provide discretion on the duration is a mandatory sentence. A mandatory sentence is defined by law, specifying that certain crimes carry a specific minimum or fixed sentence that judges must impose upon conviction. This removes any discretion from the judge regarding the length of the sentence, ensuring that the punishment is uniformly applied for specific offenses.

In contrast, an indeterminate sentence allows for a range of time during which an offender may be incarcerated, leaving the actual duration to be determined by parole boards or other authorities based on rehabilitation and behavior considerations. An enhancement sentence typically refers to a situation where a defendant receives a more severe penalty based on prior convictions or aggravating factors, but again this involves some degree of judicial discretion. Concurrent sentences refer to multiple sentences that are served at the same time rather than consecutively, which does not touch upon the issue of discretion in duration. Thus, the clarity and lack of discretion in a mandatory sentence make it the correct choice.
