The frontal bone is the correct answer because it is the bone that forms the forehead and the upper part of the eye sockets. This bone plays a crucial role in protecting the frontal lobes of the brain and gives structure to the face. The frontal bone is also important for various functions such as the formation of the skull, providing attachment points for muscles, and contributing to facial aesthetics.

In contrast, the occipital bone is located at the back of the skull and is primarily involved in protecting the brain and supporting the spinal column. The temporal bone, found on the sides of the skull, encases structures of the inner ear and houses the auditory system. The sphenoid bone is situated at the base of the skull and contributes to the structure of the eye socket and cranial base, but it does not form the forehead. Thus, the importance of the frontal bone in forehead formation makes it the correct choice.
