Which structure forms the outer fibrous coat of the eye?

Explanation:
The outermost protective layer of the eye is the fibrous tunic, which includes two parts: the sclera and the cornea. The sclera forms the thick, opaque white coat that surrounds most of the eyeball, giving it shape and providing attachment for the extraocular muscles. The cornea is the clear front window that lets light in and helps with focusing, but it is not the main protective outer boundary. The retina is the inner neural layer, and the iris is a colored diaphragm within the middle layer. So, the structure that forms the outer fibrous coat is the sclera.
