Verified step by step guidance

Begin by understanding the location of each bone mentioned in the options. The temporal bone is located on the sides of the skull, near the ears.

The ethmoid bone is a small, spongy bone located between the eyes, forming part of the nasal cavity and the orbits of the eyes.

The sphenoid bone is a butterfly-shaped bone situated at the base of the skull, in front of the temporal bones and basilar part of the occipital bone.

The lacrimal bone is a small bone forming part of the eye socket, located near the tear ducts.

To determine which bone is the most deeply situated, consider the position of each bone relative to the center of the skull. The ethmoid bone, being centrally located and forming part of the nasal cavity, is the most deeply situated bone among the options provided.
