Which statement best describes OA grade 4 features?

Explanation:
In advanced OA, radiographic severity is shown by marked changes: large osteophytes, significant loss of joint space with deformity, and subchondral sclerosis. The description that mentions large osteophytes together with sclerosis and deformity best fits grade 4, the most severe stage. The other options describe milder features (small osteophytes, no joint space narrowing, or only minor osteophytes) that align with earlier grades, not the end-stage changes seen in grade 4.
