Verified step by step guidance

Begin by understanding the anatomy of the eye, which consists of three main layers: the fibrous layer, the vascular layer, and the inner layer.

The fibrous layer is the outermost layer of the eye, primarily responsible for protection. It includes the sclera and cornea, which provide structural support and a barrier against external elements.

The vascular layer, also known as the uvea, contains the choroid, ciliary body, and iris. While its primary function is to supply blood to the eye, it also contributes to protection by maintaining the health of the eye tissues.

The inner layer, or retina, is mainly involved in processing visual information. It does not directly contribute to the protection of the eye but is crucial for vision.

Evaluate the options given: 'Fibrous Layer' and 'Inner Layer' both contribute to protection, with the fibrous layer being the most significant. Therefore, both A and C are correct in terms of protective function.
