Among the given options, find the odd one out:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Ulna
Option (1) Ulna — a long bone of the forearm, on the side of the little finger; it is not in the ear, so the ulna is the odd one out.
Option (2) Malleus — the hammer-shaped ear ossicle, joined to the eardrum.
Option (3) Incus — the anvil-shaped ear ossicle in the middle of the chain.
Option (4) Stapes — the stirrup-shaped ear ossicle, the smallest bone in the human body.
