Final answer:
The ethmoid bone is the thinnest and most frequently fractured cranial bone.
Among the cranial bones, the ethmoid bone is recognized as one of the thinnest and most commonly fractured.
So The correct answer is B) ethmoid
Step-by-step explanation:
The ethmoid bone, situated between the eyes at the base of the skull, is relatively thin compared to other cranial bones. This thinness makes it more susceptible to fractures, especially in cases of facial trauma or injury. The ethmoid bone contributes to the formation of the eye sockets and the nasal cavity.
Due to its delicate structure, it is more prone to fractures when external force is applied to the face or head, making it one of the most frequently fractured cranial bones.
The correct answer is B) ethmoid
