Which bone forms part of the orbit?

Explanation:
The orbit is a complex bony socket formed by multiple skull bones, with the zygomatic bone being one of the key contributors. The zygomatic bone helps form the lateral wall of the orbit and part of the orbital rim, giving the eye socket its outward contour and support. While the frontal bone also contributes to the orbit (forming the roof), the clavicle and fibula are not involved in the orbital structure. Among the options, the zygomatic bone clearly participates in forming the orbit, making it the correct choice.
