What is a call-to-action button?

A call-to-action button serves as a prompt for users to take specific actions, such as signing up for a newsletter, making a purchase, or downloading an app. Its primary purpose is to guide users toward an intended outcome, facilitating interaction and engagement with the website or application. This button often stands out visually to attract attention and encourage clicks, using compelling language that makes the desired action clear.

While other options describe elements that may be present on a website, they do not capture the functional essence of a call-to-action button. For instance, visual appeal is important in web design but does not define the purpose of a call-to-action. Similarly, navigation elements help users move through a site, but they differ fundamentally from a call-to-action which is specifically designed to drive user behavior and conversion goals. Lastly, a decorative element might enhance the aesthetic of a website but lacks the functional intent of prompting user actions, making the clear identification of option B essential.
