He was ordered to make___ to the victim for his crime A. Compulsory
B. Curtail
C. Restitution
D. Codify

C. Restitution

Explanation:

Answer choice C is the only correct answer in this sentence because the other words have meanings which make no sense here.

Compulsory means  "Required by law or a rule; obligatory" which may seem correct at first from the meaning but it is an adjective and wouldn't be used to describe in the missing slot.

Curtail means to "reduce in extent or quantity; impose a restriction on" and is a verb and additionally doesn't make sense for someone to "make curtail"

Restitution is correct here since it means "recompense for injury or loss" and since it is a noun it works here as "make" is already the verb and a subject is needed to make sense.

Codify means "arrange (laws or rules) into a systematic code" which simply has nothing to do with subject of the sentence which is to make amends with a victim.
