The number of bones in the human skull is –

Correct answer: (a) 28

Explanation

The human skull has 22 bones: 8 cranial bones around the brain and 14 facial bones. Counting the six ear ossicles (three in each middle ear) gives 28, and adding the hyoid bone gives 29.

So 28 is the only option that fits a usual count.

The skull has 22 bones, or 28 with the six ear ossicles (29 with the hyoid). The book marks the question as having no correct option.
