The change management approach that typically involves the use of a consultant is B. action research.

Explanation:

1. Kotter’s eight-step plan: This is a structured method for managing change but doesn't inherently require a consultant.
2. Action research: This approach often involves an external consultant who helps an organization analyze its issues and implement change based on research findings.
3. Lewin’s three-step model: This model is more of a framework for understanding change, where a consultant may not be necessary.
4. Appreciative inquiry: While it can involve external facilitators, it is focused on strengths and positive aspects rather than being consultant-driven.

In conclusion, the action research approach is distinct in its emphasis on collaborative problem-solving, often supported by external expertise, which is why it’s commonly associated with the involvement of consultants.
