Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks us to define what fluids are by choosing the correct option from the given choices.

2. **Definition of Fluids**: Fluids are defined as substances that can flow. This includes both liquids and gases.

3. **Identifying the Options**: We need to look at the options provided to determine which one correctly describes fluids.

4. **Analyzing the Options**:
- If the options include "liquids only," "gases only," "gases and liquids," and "solids," we can eliminate the last two options because solids do not flow.
- Since both liquids and gases can flow, the correct option would be the one that states "gases and liquids."

5. **Selecting the Correct Option**: Based on the analysis, the correct response is that fluids are "gases and liquids."

**Final Answer**: Fluids are gases and liquids.
