Answer:
A. Harshly rebuking their daughter upon detection of the stolen beer
Step-by-step explanation:
B.F. Skinner's theory on operant conditioning gave the concept of positive punishment. Punishment is given with goal to decrease the behavior of the individual that it follows.
In operant conditioning, positive punishment means to add something in order to decrease the likelihood in the behavior. Positive punishment is the method of adding an undesirable stimulus to lower or decrease a behavior.
Thus in the context, when Amanda's parents caught her stealing beer from the store, the parents should rebuke her so that she does not repeat the behavior in the future. Thus this shows that giving negative stimulus helps to decrease the behavior in the future, which is known as positive punishment.
Thus the correct option is --- option (A).
