What bones articulate with the distal sesamoid bone?

The distal sesamoid bone (navicular bone) sits behind the coffin joint and serves as a pulley for the deep digital flexor tendon. It forms articulation with the two bones at the end of the digit that meet there—the second and the third phalanges. That’s why the correct pairing is the second and third phalanges. The other options don’t fit because the navicular bone does not directly contact the first or fourth phalanges (or form a joint with a distal/proximal pairing outside the P2–P3 region); its contact is specifically between P2 and P3, fitting the anatomy of the coffin joint.
