The correct Answer is:
To solve the question of identifying the false statement, we will analyze each option provided in the question step by step. ### Step 1: Analyze the First Statement **Statement:** Iris muscles control the amount of light that falls on the lens of the eye. - **Explanation:** The iris is indeed the colored part of the eye that regulates the size of the pupil, which in turn controls the amount of light entering the eye. This statement is correct. ### Step 2: Analyze the Second Statement **Statement:** Pupil controls passage of light in the eye. - **Explanation:** The pupil is the opening in the center of the iris and its size changes to allow more or less light to enter the eye. This statement is also correct. ### Step 3: Analyze the Third Statement **Statement:** Choroid layer is partially modified to form iris. - **Explanation:** The choroid is a layer of blood vessels and connective tissue between the retina and the sclera. It is partially modified to form the iris, which is true. This statement is correct. ### Step 4: Analyze the Fourth Statement **Statement:** Eye color is due to pigment present in the lens. - **Explanation:** Eye color is actually determined by the amount and type of pigments present in the iris, not the lens. The lens is transparent and does not contribute to eye color. Therefore, this statement is false. ### Conclusion Based on the analysis of all the statements, the false statement is: **Eye color is due to pigment present in the lens.** ### Final Answer **The false statement is:** Eye color is due to pigment present in the lens. ---
