The correct answer is the following: The correct classification of crimes that goes from most severe to least severe is felonies, misdemeanor and inchoate offenses. A felony is tipically defined as a crime punishable only by imprisonment of one year or more. Misdemeanors on the other hand, are offenses punishable by fines or by an imprisonment in jail of less than a year long. Lastly, an inchoate offense is an incomplete crime, most of the times being defined as an attempt to commit an offense or crime.
