B) MVV
C) FEF₂₀₀‑₁₂₀₀
D) FVC

FEF 25-75% is the forced expiratory flow between 25% and 75% of the FVC maneuver. This measurement reflects the status of medium to small airways, as it measures the flow rate during the middle portion of a forced expiration. The other options do not specifically target medium to small airways; MVV reflects the maximum amount of air that can be moved in and out of the lungs, FEF₂₀₀‑₁₂₀₀ reflects the air flow rate during inhalation or exhalation at specific points, and FVC reflects the maximum amount of air that can be forcefully exhaled after a full inhalation.
