Verified step by step guidance

Step 1: Begin by understanding the context of the question. The problem is asking for the smallest bone in the human body, which requires knowledge of skeletal anatomy.

Step 2: Recall that the stapes is one of the auditory ossicles located in the middle ear. It is the smallest and lightest bone in the human body, playing a crucial role in transmitting sound vibrations to the inner ear.

Step 3: Compare the stapes to the other options provided: Maxilla, Mandible, and Hyoid. The maxilla and mandible are large bones of the skull and jaw, respectively, while the hyoid is a U-shaped bone in the neck that supports the tongue and is larger than the stapes.

Step 4: Confirm that the stapes is indeed the smallest bone by reviewing its dimensions and function. It measures approximately 3 mm in length and weighs about 2-4 mg, significantly smaller than the other bones listed.

Step 5: Conclude that the correct answer is 'Stapes' based on anatomical evidence and comparison with the other options provided.
