Which bone forms part of the orbit?

Explanation:
The orbit is formed by several skull bones, with the frontal bone contributing the roof and part of the upper boundary. Among the options, the frontal bone is the one that forms part of the orbit, making it the correct choice. The humerus, tibia, and radius are long bones of the limbs and do not participate in forming the eye socket. Understanding these boundaries helps visualize how injuries to the forehead can involve the orbital roof.
