Which of the following represents an example of an intangible asset?

A patent exemplifies an intangible asset because it represents a non-physical asset that provides a competitive advantage and potentially generates future economic benefits to a company. Intangible assets are identifiable non-monetary assets without physical substance. They include intellectual properties like patents, copyrights, trademarks, and goodwill.

In contrast, inventory is a tangible asset since it consists of physical goods held for sale. Plant and equipment are also tangible assets, representing physical assets used in the production of goods and services. Cash is considered a monetary asset, as it represents currency available for transactions. Thus, among the choices, a patent clearly fits the definition and characteristics of an intangible asset.
