Explanation

Validation studies for lyophilization must evaluate shelf temperature and sublimation rates (A) because these are the critical process parameters that directly determine whether the freeze-drying cycle successfully removes moisture while preserving product stability, potency, and sterility - the core goals of lyophilization validation. B (product color) is a final product attribute, not a process parameter being validated during the cycle itself. C (employee popularity) is entirely irrelevant to process science or regulatory requirements. D (facility layout) is addressed in facility qualification, not lyophilization process validation specifically.

Memory tip: Think "FREEZE = Function of Temperature" - lyophilization validation centers on the thermal and physical mechanics of the process (shelf temp drives ice sublimation), not appearance, opinions, or facility design.
