The correct Answer is:
To solve the question regarding the assertion and reason provided, we will break down the statements step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Cones of retina help in colour vision." - Cones are indeed photoreceptor cells located in the retina that are responsible for color vision. They function best in bright light conditions and are essential for detecting fine details and colors. 2. **Understanding the Reason**: - The reason states that "Different types of cones are stimulated by different radiations of the visible light." - There are three types of cones in the human retina: S-cones (sensitive to blue light), M-cones (sensitive to green light), and L-cones (sensitive to red light). Each type of cone responds to specific wavelengths of light, which correspond to different colors. 3. **Analyzing the Relationship**: - The assertion is true because cones do play a crucial role in color vision. - The reason is also true as it explains how the different types of cones respond to various wavelengths of visible light, which is fundamental to color perception. 4. **Conclusion**: - Since both the assertion and reason are true, and the reason correctly explains the assertion, the correct answer is: "Both assertion and reason are true, and reason is the correct explanation of assertion." ### Final Answer: Both assertion and reason are true, and reason is the correct explanation of assertion. ---
