D. none of these

Answer

To solve the question "A football is an example of", we will analyze the options provided:

### Step 1: Understand the shapes
- We have four options to consider:
1. Cylinder
2. Cone
3. Sphere
4. None of these

### Step 2: Define each shape
- **Cylinder**: A three-dimensional shape with two parallel circular bases connected by a curved surface. Example: A can of soda.
- **Cone**: A three-dimensional shape with a circular base that tapers smoothly from the base to a point called the apex. Example: An ice cream cone.
- **Sphere**: A perfectly round three-dimensional shape where every point on the surface is equidistant from the center. Example: A basketball or a football.
- **None of these**: This option indicates that the correct answer is not listed among the previous options.

### Step 3: Analyze the football
- A football is a round object that is used in the game of football (soccer). It is designed to be kicked and is typically spherical in shape.

### Step 4: Match the football with the options
- Comparing the shape of a football with the definitions:
- A football does not have the characteristics of a cylinder or a cone.
- A football fits the definition of a sphere perfectly.

### Step 5: Choose the correct option
- Since a football is round and fits the definition of a sphere, the correct answer is **Option 3: Sphere**.

### Final Answer
- Therefore, a football is an example of a **sphere**.
