The rotating passages of a reaction turbine are mounted on which component?

Explanation:
Rotating passages are the moving blades, and they must spin with the shaft. They are fixed to the rotor disk so the blades rotate with the turbine. Stationary blades are mounted in the diaphragm or the casing, not on the rotor. A shroud ring surrounds the blade tips to reduce leakage and stiffen the row, but the blades themselves are still mounted on the rotor. So the rotating passages are mounted on the rotor.
