Which bone participates in forming the zygomatic arch?

Explanation:
The zygomatic arch is formed by two bones: the zygomatic bone and the temporal bone (through the temporal process). The zygomatic bone contributes a key portion of the arch, giving the cheek its prominence and forming part of the lateral boundary of the orbit. The lacrimal bone lies in the medial orbital wall and the sphenoid does not form this arch, while the temporal bone also participates via its own zygomatic process. So the bone listed that participates in forming the zygomatic arch is the zygomatic bone.
