Which of the following does NOT demonstrate agile thinking?

Comprehensive and Detailed Explanation (paraphrased from Agile Project Management guidance):

Agile thinking emphasizes customer value, empirical evidence, collaboration, and transparency. Option A reflects progressive elaboration and just-in-time refinement—good agile practice. Option B suggests a typical, lightweight cadence for readiness (often the Sprint prior), which is acceptable when driven by context and team capacity rather than rigid rule. Option C captures the essence of flow through small, frequent, validated increments. Option D, however, bypasses value-based prioritization, team forecasting, and collaborative decision-making by selecting the next Sprint’s work purely on sponsor preference. Agile approaches (e.g., MoSCoW prioritization, product goals, acceptance criteria) rely on shared, objective value measures, not unilateral authority, to maximize outcomes. Therefore, D does not demonstrate agile thinking.
