The judge used his . . . . . . . . power and let him off with a reprimand.

The correct answer is E, discretionary.

A discretionary power is a power that is given to an individual or group to make a decision on how to act in a particular situation. In this case, the judge used his discretionary power to decide whether to sentence the defendant to

jail or to let him off with a reprimand.

The other options are incorrect because

they do not accurately describe the judge’s power. A residuary power is a power that is left over after all other powers have been assigned. An official power is a power that is given to an individual or group by the government. A legal power is a power that is granted by law. An absolute power is a power that is not limited by any rules or regulations.

In conclusion, the judge used his discretionary power to let the defendant off with a reprimand.
