Choose the correct statement from the following.

Options

A. Light causes sensation of vision.
B. The sensation of heat is due to the presence of infrared radiation.
C. Light travels in a straight line.
D. All the above

Explanation

To solve the question of choosing the correct statement regarding light, we will analyze each statement provided.

### Step-by-Step Solution:

1. **Understanding the First Statement**:
- The first statement is "Light causes sensation of vision."
- This is true because vision is only possible when light reflects off objects and enters our eyes. Without light, we cannot see anything.

**Hint**: Think about what happens when you turn off the lights in a room. Can you see anything?

2. **Analyzing the Second Statement**:
- The second statement is "The sensation of heat is due to the presence of IR radiation."
- This statement is also correct. Infrared (IR) radiation is a type of light that we cannot see, but it is responsible for the sensation of heat. When we feel warmth from sunlight, it is primarily due to IR radiation.

**Hint**: Consider how you feel warmth from a heater or the sun, even if you can't see the radiation itself.

3. **Evaluating the Third Statement**:
- The third statement is "Light travels in a straight line."
- This statement is true as well. Light does travel in straight lines unless it encounters a medium that causes it to bend (refraction) or an obstacle that blocks it, creating shadows.

**Hint**: Recall how shadows are formed when an object blocks light. What does that tell you about the path of light?

4. **Conclusion**:
- Since all three statements are correct, the answer to the question is that all of the above statements are true.

**Final Answer**: All of the above statements are correct regarding light.
