The correct answer is Paraphrasing.

Paraphrasing is a counseling skill that involves reflecting back what the client says and feels using different words. This helps the client to feel heard and understood, and it can also help the counselor to identify the client's core emotions and concerns.

Empathy, authenticity, and unconditional positive regard are all important qualities for counselors to have, but they are not the same as paraphrasing. Empathy is the ability to understand and share the feelings of another person. Authenticity is the ability to be genuine and true to oneself. Unconditional positive regard is the acceptance of another person without judgment.

Paraphrasing is a specific skill that can be learned and practiced. It is an important tool for counselors because it can help to build rapport with clients, promote understanding, and facilitate change.
