AQuill shaft
BExpansion gear
CSliding sleeve
DGear-type flexible coupling
AI Explanation
The correct answer is D) Gear-type flexible coupling. A gear-type flexible coupling is commonly used to compensate for the expansion and minor misalignments that occur between the main turbine rotor and the reduction gear. This type of coupling allows for a small amount of angular and lateral movement between the two connected components, preventing damage that could occur due to thermal expansion or slight misalignment. The other options, such as a quill shaft, expansion gear, or sliding sleeve, are not specifically designed for this purpose.
