In the right hip arthroplasty case, which components were implanted?

In a hip replacement, the acetabular cup and the femoral head must fit together: the cup has an outer diameter and an inner bore that must match the head size. A 52 mm outside diameter cup with a 36 mm inside diameter head means the head is 36 mm and sits inside that cup. Specifying a metal-on-metal head indicates the bearing surface is metal against metal, which is typical for larger-diameter heads like 36 mm. The stem size (10.5) completes the femoral component. So this option reflects a 52/36 acetabular cup with a 36 mm metal-on-metal head and a 10.5 stem, which matches a common MoM total hip arthroplasty configuration. The other choices either pair mismatched head sizes with the cup bore, omit the MoM bearing, or describe a cemented stem not consistent with the described case.
