\begin{tabular}{l} An example of a factor of production is \\ O the computers exported by Dell. \\ O stock issued by Dell. \\ O a worker hired by Dell. \\ \hline\end{tabular}

To determine which option is an example of a factor of production, we need to understand what factors of production are. Factors of production are the resources used to produce goods and services. They typically include: 1. **Land**: Natural resources used in production. 2. **Labor**: Human effort used in production. 3. **Capital**: Man-made resources (like machinery, tools, and buildings) used in production. 4. **Entrepreneurship**: The ability to combine the other factors of production to create goods and services. Now, let's analyze the options provided: 1. **The computers exported by Dell**: This refers to the final product, not a factor of production. 2. **Stock issued by Dell**: This represents ownership in the company and is a financial instrument, not a factor of production. 3. **A worker hired by Dell**: This represents labor, which is a direct factor of production. Based on this analysis, the correct answer is: **A worker hired by Dell.**
