Verified step by step guidance

Step 1: Understand the anatomy of the cranial bones. The human skull is composed of several cranial bones, each with specific locations and functions. Familiarize yourself with the names and positions of these bones: frontal, parietal, temporal, occipital, etc.

Step 2: Focus on the frontal bone. The frontal bone is located at the front of the skull and plays a key role in forming the forehead, the bony eyebrow ridges (also known as the supraorbital margins), and the roofs of the orbits (eye sockets).

Step 3: Compare the functions of the other cranial bones listed in the options. The parietal bone forms the sides and roof of the cranial cavity, the temporal bone is located on the sides of the skull and houses the structures of the ear, and the occipital bone forms the back and base of the skull.

Step 4: Eliminate incorrect options based on their anatomical locations and functions. Since the parietal, temporal, and occipital bones do not contribute to the formation of the bony eyebrow ridges or the roofs of the orbits, they can be ruled out.

Step 5: Conclude that the frontal bone is the correct answer, as it is the cranial bone responsible for forming the bony eyebrow ridges and the roofs of the orbits.
