Anotch and keyway
Bbellows
Cspring
Dseal retaining ring
AI Explanation
The correct answer is C) spring. The spring is used to maintain a snug interface between the rotating and stationary seal members shown in the illustration. The spring applies constant pressure to keep the seal components tightly fitted together, preventing leaks and maintaining the proper seal. The other options are incorrect because: A) a notch and keyway are used to align and secure components, not to maintain a seal; B) a bellows is a flexible component that can expand and contract, not a mechanism to maintain a seal; and D) a seal retaining ring is used to hold the seal in place, not to create the snug interface between the seal members.
