When is it most beneficial to clear your browser's cache of temporary Internet files?

Clearing your browser's cache of temporary Internet files is particularly beneficial when a website is not functioning properly. This is because cached files can sometimes become outdated or corrupted, causing inconsistencies in how a webpage is displayed or how it operates. When you revisit a website, the browser may load the cached version rather than retrieving fresh content from the server. If that cached data is no longer valid or has changed on the server side, clearing the cache forces the browser to load the most recent version of the website, which can resolve issues such as pages not loading correctly or elements not displaying as intended.

In other scenarios, while clearing the cache may provide some benefits—like deleting browsing history or freeing up storage—these are not primarily targeted towards resolving website functionality issues. Clearing the cache is specifically useful for troubleshooting site performance, which aligns directly with option B.
