Final answer:
The best question to ask an adolescent to encourage conversation is "How is school going for you?" as it is open-ended and focuses on their personal experiences.
Step-by-step explanation:
When interviewing an adolescent to encourage conversation, the most appropriate question is c. "How is school going for you?" This question is open-ended and invites the student to share more than just a yes or no response. It allows the adolescent to reflect on their personal experiences and perceptions of school, which can lead to a more engaging and extended conversation. Asking about their own views rather than imposing external viewpoints (such as how their parents feel about their grades) facilitates a more comfortable dialogue, as the focus remains on the adolescent's own experiences and feelings.
