Question

what behavior should a teen engage in to gain support for abstinence from trusted adults?
join a club or sport
avoid triggering situations
discuss boundaries with your partner
connect with family or a counselor

Explanation:

The question asks for a behavior to gain support for abstinence from trusted adults. Connecting with family (trusted adults) or a counselor (a trusted professional) directly facilitates seeking and receiving such support. The other options do not focus on engaging trusted adults for support: joining a club/sport is general social engagement, avoiding triggering situations is a personal strategy, and discussing boundaries with a partner is between peers.

Answer:

connect with family or a counselor
