Final answer:
The term for crimes that go unreported, such as the robbery Jane experienced, is 'Dark figure of crime'. It points to the gap between actual and reported crimes.
Step-by-step explanation:
The crime described in the student's question, where Jane is robbed and she does not report it to the police, would most likely be classified under the term B) Dark figure of crime. This term refers to crimes that go unreported and therefore are not included in official crime statistics. It represents the discrepancy between the actual number of crimes committed and the number of crimes reported to or discovered by the police. In contrast, repeat offenses are crimes that occur multiple times. Victimless crimes involve activities that are illegal but do not directly violate or threaten the rights of any other individual, and white-collar crime tends to refer to financially motivated, nonviolent crime committed by business and government professionals.
