Final answer:
The correct option is C). Trade secrets are a type of intangible property that businesses protect to maintain an economic advantage, exemplified by the formula for Coca-Cola.
Step-by-step explanation:
Among the options provided, trade secrets are a type of intangible property that businesses often establish policies to protect. A trade secret can consist of a formula, practice, process, design, instrument, pattern, or compilation of information that is not generally known or reasonably ascertainable, by which a business can obtain an economic advantage over competitors or customers. A classic example of a trade secret is the formula for Coca-Cola, which is famously kept undisclosed. Inventories, production systems, and delivery routes, while they may be proprietary to a specific business, are not typically considered trade secrets in the same manner.
