Verified step by step guidance

Step 1: Begin by understanding the fibrous layer of the eye. The fibrous layer is the outermost layer of the eye and consists of two main components: the sclera (the white part of the eye) and the cornea (the transparent part at the front of the eye). It provides structural support and protection for the eye.

Step 2: Recognize the functions of the fibrous layer. It serves as an attachment site for the extrinsic eye muscles, which are responsible for moving the eyeball. Additionally, the fibrous layer is avascular, meaning it does not contain blood vessels.

Step 3: Compare the given statements to the known characteristics of the fibrous layer. The first three statements are true: it provides structural support and protection, serves as an attachment site for extrinsic eye muscles, and consists of the sclera and cornea.

Step 4: Evaluate the fourth statement: 'contains blood vessels that nourish the retina.' This is incorrect because the fibrous layer is avascular. Blood vessels that nourish the retina are found in the vascular layer (also called the uvea), which includes the choroid, ciliary body, and iris.

Step 5: Conclude that the correct answer is the fourth statement, as it does not align with the known characteristics of the fibrous layer of the eye.
