Final answer:
The correct operant contingency is option d. Antecedent-behavior-consequence represents the operant conditioning model where consequences shape the occurrence of behaviors.
Step-by-step explanation:
An operant contingency is a fundamental concept within operant conditioning, a form of associative learning where behavior is shaped by its consequences. Among the listed options, the one that represents an operant contingency is d. Antecedent-behavior-consequence. In this model, an antecedent triggers a behavior, which is then followed by a consequence. The consequence then influences the likelihood of the behavior occurring again in the future, either reinforcing or punishing the behavior. For example, B. F. Skinner's experiments with rats and pigeons demonstrated how operant conditioning can be used to systematically strengthen or weaken behaviors through reinforcements or punishments.
