Which of the following best defines web browsing history?

The term "web browsing history" specifically refers to a log of websites that a user has visited over a certain time period. This record is automatically created by web browsers to help users keep track of their online activities. It can be consulted to re-access previously visited pages or to clear it for privacy.

While the other options mention elements related to a web browsing experience, they don't specifically define browsing history. Files downloaded refers to items saved from the internet, a saved cache of images pertains to temporary storage of media for quicker loading times, and a list of bookmarked pages involves user-selected favorites which can be accessed easily but do not represent the complete history of all browsing activities. Browsing history encompasses a chronological list of all the different websites a user has visited, making it distinct from these other options.
