In an expert system, the expertise is primarily contained in the **knowledge base**. This component stores the facts, rules, and heuristics that the system uses to make inferences and provide solutions to problems.

To evaluate the options provided:

1. **Any of the above**: This option suggests that expertise could be found in more than one element, which is not accurate as the primary source is the knowledge base.
2. **Knowledge base**: Correct answer, as this is where all the domain-specific knowledge resides.
3. **Model based**: While model-based systems may utilize knowledge, they do not contain the expertise directly.
4. **Database**: Generally serves to store data rather than specifically expert knowledge.

### Final Answer
