• A. stators
• B. buckets
• C. rotors
• D. shrouds

Answer: (A)

When you have a row of stationary blades between rotating rows, those blades are stators. They’re fixed to the casing and act as vanes to guide and diffuse the airflow, turning its direction and converting some of the air’s velocity into pressure for the next stage. This sets up the next rotor to operate efficiently. Buckets refer to the rotor blades, rotors are the rotating assemblies, and shrouds are the tip or casing structures around blades—none of those are the stationary diffusion blades.
