Answer 1

Answer: (C)

The outermost layer of the eyeball is fibrous in nature. The two-third part of this layer is opaque and lies inside the eye orbit and is known as the sclera. The remaining one-third of the outer layer is transparent and bulges out to form the cornea. There is no supply of blood in the cornea.
