Step 1: Understanding the Concept:
Factors of production are the inputs or resources that are used in the production process to produce output, i.e., goods and services.
Step 2: Detailed Explanation:
In modern economics, the factors of production are traditionally classified into four main categories:
\begin{enumerate}
\item Land: This includes all natural resources, not just the physical ground, but also minerals, water, forests, etc. The payment for land is rent.
\item Labor: This refers to the human effort, both mental and physical, used in the production process. The payment for labor is wages.
\item Capital: This includes all man-made resources used in production, such as machinery, tools, buildings, and technology. The payment for capital is interest.
\item Entrepreneurship: This refers to the skill and risk-taking ability of the person who brings the other three factors together to produce a good or service. The payment for entrepreneurship is profit.
\end{enumerate}
While some economists might consider technology or information as a fifth factor, the standard and most widely accepted classification includes four factors.
Step 3: Final Answer:
There are four main factors of production in the modern age. Therefore, option (C) is correct.
