Final answer:
In conflict resolution, a constructive and active response is Reaching out, as it engages dialogue towards a resolution, unlike competitive or negative responses.
Step-by-step explanation:
In a conflict situation, a constructive and active response that would be most beneficial is B) Reaching out. This response involves initiating dialogue, seeking to understand the other party's perspective, and working towards a resolution that addresses the concerns of all involved. It contrasts with responses that are competitive (like C) Winning), negative (like D) Self-criticizing), or passive. While reflective thinking and adapting are valuable skills, reaching out is more active and directly targets conflict resolution. Reflective thinking helps to identify cognitive biases and can also contribute to resolving conflicts by improving self-awareness and promoting a more analytic approach to problems. Adapting can be useful in adjusting to new situations and overcoming barriers, but it is reaching out that most clearly represents an active, constructive effort to engage another person or group to resolve a dispute.
