Explanation:

The endosteum is a thin membrane that lines the inner surface of the bone's medullary cavity, which is the central hollow space inside long bones. The cortex is the hard outer layer of bone, so the endosteal surface is not on or within the cortex, nor at the corticomedullary junction (the boundary between cortex and medulla).

Answer:

D. within the medullary cavity
