Answer:
The correct answer is option B) DRO
Step-by-step explanation:
Julie's teacher must operationalise differential reinforcement of other behaviors.
The reason is that differential reinforcement of other behavior is only focused on a particular behavior that is not required and is supposed to be gotten rid of. Reward is only given when that particular behavior is NOT shown by the person in that selected period of time.
Therefore Julie's teacher should reward her when she does not dominate the class discussions as part of DRO.
