Requirements prioritization and negotiation belongs to :

Answer: Requirements elicitation

Why this is correct: Prioritization and negotiation are performed while gathering and agreeing requirements with stakeholders to resolve conflicts and determine which requirements are most important.

• Key activities in elicitation: stakeholder interviews, workshops, negotiation, and prioritization techniques (for example, MoSCoW, ranking).

• Feasibility studies evaluate whether a solution is viable technically, economically, or operationally, but they do not primarily perform stakeholder negotiation of requirements.

• Validation and reviews check that requirements are correct, complete, and testable after they have been captured; they focus on quality rather than negotiating priorities.

Memory aid: elicitation = collect and agree; validation = confirm; feasibility = can we; reviews = quality check.
