Which option is NOT an example of capital in a business?

Human resources refer to the workforce or personnel employed by a business, encompassing their skills, expertise, and experiences. While crucial for the operation and success of a business, human resources are not categorized as capital in the same way that physical and financial assets are. Capital typically includes tangible and intangible assets that are used in the production of goods and services; this includes machinery, buildings, and cash.

Machinery and buildings are physical assets that directly contribute to production capacity, while cash acts as a financial resource that can be utilized for investments or day-to-day operations. In contrast, human resources are considered a factor of production rather than a type of capital asset, which is why this option stands out from the others.
