How does a loading spinner enhance user experience?

A loading spinner enhances user experience primarily by indicating that content is loading. This visual cue reassures users that the website or application is actively working on their request, which is particularly important in situations where loading times may be longer than expected. When users see the spinner, they understand that the system is processing their request, which helps to reduce frustration and uncertainty.

This kind of feedback is crucial in maintaining user engagement, as it keeps users informed rather than leaving them guessing about whether the application is functioning properly. While providing user feedback is also a valid concept, the specific role of the loading spinner is to signify the loading state of content, thus making option B the most accurate answer in this context. Other options like playing background music or providing navigation options are unrelated to the fundamental purpose of a loading spinner.
