Explanation:
Correct Option: B. HXLPE is manufactured by irradiating the polymer to create cross-links between the carbon chains. This structural change significantly improves the material's resistance to adhesive and abrasive wear at the articular surface, which are the primary generators of the submicron particles that trigger osteolysis.
