Solution

The correct option is D Temporal bone
The temporal bone contributes to the lower lateral walls of the skull. It contains the middle and inner portions of the ear and is crossed by the majority of the cranial nerves. The lower portion of the bone articulates with the mandible and forms the temporomandibular joint of the jaw. So, the correct answer is 'Temporal bone'.
