Choose the correct statement :

Options

A. every line has a definite length
B. every ray has a definite length
C. every line segment has a definite length
D. None of these

Answer

To solve the question "Choose the correct statement," we need to analyze each of the provided options regarding lines, rays, and line segments.

### Step-by-Step Solution:

1. **Understanding the Definitions**:
- **Line Segment**: A line segment has two endpoints and a fixed length. For example, if we have points A and B, the line segment AB is the distance between A and B, and it cannot be extended beyond these points.
- **Ray**: A ray has one endpoint and extends infinitely in one direction. For example, if we have point A and it extends infinitely towards point B, we denote this as ray AB. It does not have a definite length because it continues forever.
- **Line**: A line extends infinitely in both directions without any endpoints. It has no fixed length as it can be extended indefinitely in either direction.

2. **Analyzing Each Statement**:
- **Every line has a definite length**: This is incorrect because a line extends infinitely in both directions.
- **Every ray has a definite length**: This is also incorrect because a ray extends infinitely in one direction.
- **Every line segment has a definite length**: This is correct because a line segment has two endpoints and a fixed distance between them.
- **None of these**: This option is incorrect since we have already identified a correct statement.

3. **Conclusion**:
- The correct statement is: **"Every line segment has a definite length."**

### Final Answer:
**Every line segment has a definite length.**
