Answer:
C. Machiavelli uses logical evidence to assert that it is acceptable for new princes to use cruelty.
Step-by-step explanation:
Quote from Machiavelli: "Nevertheless he ought to be slow to believe and to act, nor should he himself show fear, but proceed in a temperate manner with prudence and humanity, so that too much confidence may not make him incautious and too much distrust render him intolerable."
All of this is objective and logical.
