The correct Answer is:
To solve the question "The central opening of iris is called as", we need to analyze each of the given options: 1. **Understanding the Question**: The question asks for the name of the central opening of the iris in the human eye. 2. **Evaluating Option (a) Cornea**: - The cornea is the transparent outer layer of the eye. - It serves as a protective layer and helps focus light, but it is not the central opening of the iris. - **Conclusion**: This option is incorrect. 3. **Evaluating Option (b) Lens**: - The lens is a transparent structure located behind the iris and is responsible for focusing light onto the retina. - It is attached to the ciliary body and is not the central opening of the iris. - **Conclusion**: This option is also incorrect. 4. **Evaluating Option (c) Pupil**: - The pupil is indeed the central opening of the iris. - It regulates the amount of light that enters the eye by constricting or dilating. - **Conclusion**: This option is correct. 5. **Evaluating Option (d) Fovea centralis**: - The fovea centralis is a small pit in the retina that contains a high concentration of cones and is responsible for sharp central vision. - It is not related to the iris and does not serve as an opening. - **Conclusion**: This option is incorrect.
