The extensor process is a feature of which bone?

Explanation:
The extensor process is a small dorsal projection on the coffin bone, which is the distal phalanx (P3) inside the hoof. It serves as the attachment point for the extensor tendon, enabling the toe to be extended. Among the bones listed, only the coffin bone carries this feature. The navicular bone sits behind and articulates with the coffin bone but does not have an extensor process, and the proximal and short pastern bones are more proximal phalanges that do not bear this projection.
