Step 1: The image shows a Giant cell tumor (GCT) of bone, also called osteoclastoma. It is a relatively common, usually benign bone tumor.
Step 2: The true radiographic features of GCT are: it arises in the metaphysis and extends into the epiphysis up to the articular surface (so options a and the epiphyseal-metaphyseal location are correct), it has a well-defined non-sclerotic margin (option b correct), and it is an eccentric lesion (option c correct).
Step 3: The treatment of GCT is surgical - curettage and packing with bone chips or polymethylmethacrylate (PMMA), not chemotherapy. Chemotherapy is not the treatment of choice.
Step 4: Therefore the incorrect statement is option d, making it the answer to a "which is incorrect" question.
