The best answer is C because PMI-PMOCP™ principles emphasize evidence-based decision-making, balanced resource management, and portfolio-level visibility. A PMO professional should not rely only on historical data, current availability, or executive preference. Effective resource allocation requires a complete view of past utilization patterns, current project health, and future demand. This enables the PMO to support informed decisions that balance capacity, priority, risk, and strategic value. Option A is incomplete because past performance alone does not reflect current constraints or future needs. Option B is overly simplistic and may misalign scarce resources with low-value work. Option D introduces bias and weakens governance by prioritizing influence over objective criteria. Combining historical, current, and forecast data supports transparent and optimized allocation decisions.
