In Babok 2, p. 101 - Prioritize Requirements: Challenges in facilitating a requirements prioritization session include: Non-negotiable Demands: Stakeholders attempt to avoid difficult choices, fail to recognize the necessity for making tradeoffs, or desire to rank all requirements as high priority. Unrealistic Tradeoffs: The solution development team may intentionally or unintentionally try to influence the result of the prioritization process by overestimating the difficulty or complexity of implementing certain requirements.

A. All requirements are ranked as high This is an example of a non-negotiable demand because it implies that all requirements must be treated as high priority, leaving no room for negotiation or prioritization based on other factors. It sets an inflexible stance that doesn't allow for trade-offs or adjustments based on different criteria such as cost, benefits, or other considerations.
