Final answer:
When witnessing bullying at school, the correct action is to tell a trusted adult, as they can handle the situation effectively and support those involved. Confronting the bully or taking revenge are not safe or constructive actions. The correct option is b: tell a trusted adult.
Step-by-step explanation:
If someone else is being bullied at school, the most appropriate action is to tell a trusted adult. This is because adults in authority positions at school, such as teachers and counselors, have the training and ability to appropriately manage the situation and to support those involved, including the victim and the witnesses. It's not advisable to confront the bully directly, as this could escalate the situation or put someone at greater risk. Additionally, taking revenge can lead to more harm and is not a constructive way to deal with bullying.
Bullying has negative consequences not only for the victim but also for the bystanders. Witnesses to bullying can experience feelings of guilt, fear, or powerlessness, and could also be at risk of being targeted themselves. By informing a trusted adult, you can help to create a safer environment for everyone involved.
The correct option in this scenario is b: tell a trusted adult. This must be the correct option in the final answer when advising someone on how to respond to witnessing bullying at school.
