To define the MVP in an agile project, it's essential to identify the highest-value features and gather input from stakeholders. MVP refers to the smallest functional product that delivers value to users.

Option D (Conducting an information-gathering session) aligns with MVP development since the value delivered is the priority in Agile.

Option E (Referring to the stakeholder register) ensures that the right stakeholders are consulted to define what "minimum" means from their perspective.

Option A (Creating a WBS) is traditional/predictive and not suitable for MVP-focused, value-driven development.

Option B (RACI) is useful for role clarity but not directly relevant to defining an MVP.

Option C (Developing a PM Plan) is broader and not MVP-specific.
