AI Explanation
The correct answer is C) permit removal of the bearing without removing the rotor from the turbine. Journal bearings used with modern turbine rotors are manufactured in two halves to allow the bearing to be removed and replaced without having to remove the entire rotor from the turbine. This design feature facilitates maintenance and repair, as the rotor can remain in place while the bearing halves are replaced as needed. The other answer choices do not directly relate to the purpose of the two-piece bearing design.
