Options

A. 1
B. 2
C. 3
D. 5

Explanation

To solve the question regarding the number of dimensions of a solid, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Dimensions:**
- Dimensions refer to the measurable extents of an object. In geometry, we commonly refer to one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D) spaces.

2. **Identifying Solid Shapes:**
- Solid shapes are three-dimensional objects. Examples include a cube, cuboid, cone, and cylinder. These shapes occupy space and have volume.

3. **Defining the Dimensions of Solids:**
- A solid has three dimensions:
- **Length:** The measurement of how long an object is.
- **Breadth (or Width):** The measurement of how wide an object is.
- **Height:** The measurement of how tall an object is.

4. **Conclusion:**
- Since solids are characterized by having length, breadth, and height, we conclude that the number of dimensions of a solid is **3**.

### Final Answer:
The number of dimensions of a solid is **3**.
