Find the number of dimension(s) a line has.

Options

A. 0
B. 1
C. 2
D. 3

Answer

To determine the number of dimensions a line has, we can follow these steps:

### Step-by-Step Solution

1. **Understanding Dimensions**:
- Dimensions refer to the measurable extents of an object. Common dimensions are length, width, and height.

2. **Identifying the Characteristics of a Line**:
- A line is a straight one-dimensional figure that extends infinitely in both directions. It has length but no width or height.

3. **Defining One-Dimensional Space**:
- One-dimensional (1D) space means that there is only one measurable extent, which is length. In a 1D space, you can only move forward or backward along the line.

4. **Conclusion**:
- Since a line only has length and lacks any other measurable extents (like width or height), we conclude that a line is one-dimensional.

5. **Final Answer**:
- Therefore, the number of dimensions a line has is **1**.
