Which of the following is a characteristic of a trademark?

A trademark is fundamentally a symbol, word, or phrase that is legally registered or established by use as representing a company or product. The characteristic that identifies and distinguishes the source of goods or services is central to the purpose of a trademark. This identification helps consumers recognize the origin of products or services and differentiate them from those of competitors, thereby playing a critical role in branding and marketing.

For example, when consumers see a particular logo or brand name, they can associate that with the quality and reputation of the goods or services offered, which is essential for maintaining consumer trust and loyalty.

The other statements do not accurately reflect the nature of trademarks. While some elements of intellectual property protection are addressed by the other choices, they do not correctly describe the distinctive nature and function of trademarks.
