Step-by-step explanation:
When a defendant is harassed and tortured until he confesses, this is an example of positive punishment. In the context of operant conditioning, positive punishment refers to adding an unpleasant stimulus to decrease a behavior, which in this case, is the defendant's resistance to confessing.
This contrasts with negative reinforcement, which involves removing an unpleasant stimulus to increase a desired behavior, not relevant in this scenario of torture to elicit a confession. The Constitution forbids such acts of torture as a form of punishment, considering it inhumane and a violation of human rights. Option d is answer
