Which of the following statements is correct regarding rods and cones in the human eye?

Options

A. Cones are sensitive to dim light
B. Cones are sensitive to bright light.
C. Rods are sensitive to bright light.
D. Rods can sense colour

Answer

To determine which statement is correct regarding rods and cones in the human eye, let's analyze the characteristics of both types of photoreceptor cells.

### Step-by-Step Solution:

1. **Identify the Functions of Rods and Cones**:
- **Rods**: These are photoreceptor cells that are highly sensitive to light and allow us to see in low-light conditions (dim light). They do not detect color.
- **Cones**: These cells are less sensitive to light compared to rods but are responsible for color vision and function best in bright light.

2. **Evaluate the Statements**:
- We need to check the statements provided in the options against the known functions of rods and cones.
- If an option states that "cones are sensitive to dim light," it is incorrect because cones are primarily sensitive to bright light.
- If an option states that "rods are responsible for color vision," it is also incorrect since rods do not detect color.

3. **Identify the Correct Statement**:
- The correct statement will highlight that cones are sensitive to bright light and are responsible for color vision, while rods are sensitive to dim light and do not detect color.

4. **Conclusion**:
- After analyzing the options, the correct statement regarding rods and cones is that **"cones are sensitive to bright light and are responsible for color vision."**
