AI Explanation
The correct answer is C) renewable sleeves.
Renewable sleeves are the most effective way to prevent permanent centrifugal pump shaft damage due to erosion, corrosion, and wear at the stuffing box.

In contrast, the other options like wearing rings, internally flooded lantern rings, or hardened coatings may not provide the same level of protection or ease of replacement.
