To determine which chemical reaction results in the formation of a solid, let's analyze each option:

1. **Acid-Base Reaction**: This type of reaction involves the neutralization of an acid and a base, often resulting in the formation of water and a salt. In some cases, a solid (precipitate) can be formed, but this is not always the case.

2. **Endothermic Reaction**: Endothermic reactions absorb heat from the surroundings, but they do not necessarily result in the formation of a solid. They can produce gases, liquids, or remain in the reactant state depending on the specific reaction.

3. **Precipitate**: This term specifically refers to the solid that forms and separates from a solution during a chemical reaction. Precipitation occurs when certain conditions are met, such as mixing two soluble salts in solution, causing an insoluble product to form.

### Conclusion:
The correct answer is **C. precipitate**, as it directly signifies a reaction that leads to the formation of a solid substance from a solution.
