Explanation

Calibration ensures an instrument produces measurements that fall within a defined range with both accuracy (closeness to true value) and precision (repeatability), which is the foundation of reliable, reproducible results - making B correct. Cost (A) is irrelevant to measurement performance; an expensive instrument can still drift out of calibration. Open access without training (C) is a safety and competency policy issue, not a function of calibration. Sample compatibility (D) depends on the instrument's design and reagent chemistry, not its calibration status.

Memory tip: Think of calibration as setting a ruler's zero mark - without it, every measurement is offset, no matter how consistently you read it. Calibration = correctness + consistency.
