Question

Quizplus · Accepted Answer

Signalling is ubiquitous, meaning it is found in many different fields and industries, including economics, biology, and telecommunications. It is a common and important concept in these areas, and not limited to just one specific application. While it can be costly in some cases, this is not always the case and therefore option D is not the best choice. Option A is incorrect as screening is different from signalling, although the two may be related in certain contexts. Option C is incorrect as signalling is not an art, but rather a concept or tool used in various fields.
