The most effective bullying interventions are those that target: a. Bullies b. Victims c. Bystanders d. Authority figures

The most effective bullying interventions are those that target all of the above. Here's why:

a. Bullies: Interventions need to address the behavior of bullies by teaching them empathy, understanding, and better ways to express their feelings and deal with conflicts.

b. Victims: Interventions should also focus on victims by providing them with support, teaching them how to respond to bullying, and helping them build their self-esteem and resilience.

c. Bystanders: Bystanders play a crucial role in bullying situations. They can either contribute to the problem or help stop it. Therefore, interventions should teach bystanders how to stand up against bullying and support the victim.

d. Authority figures: Teachers, parents, and other authority figures have a significant influence on children's behavior. They should be educated on how to recognize and respond to bullying, and how to model and reinforce positive behavior.

Therefore, the most effective bullying interventions are comprehensive programs that address all aspects of the bullying dynamic.
