What type of forensic evidence can be recovered from browser history?

The correct choice highlights the capability of browser history to provide insights into a user's online activity. When a browser records this history, it logs the websites visited, the timestamps of those visits, the duration of time spent on each page, and often any interactions made on those sites. This data can be invaluable in forensic investigations, as it offers a direct look into the behaviors and interests of an individual, revealing patterns that may be relevant in a case.

In contrast, the other options do not directly relate to the specific evidence that can be pinpointed from browser history. System settings typically pertain to configurations and preferences of the operating system rather than user activity. Cached files may contain webpage data but do not specifically record user activity as browser history does. Temporary folders, while they store transient files used by applications, do not necessarily provide insights into browsing habits or the user's online behavior. Therefore, the selection of users' online activity as the type of forensic evidence tied to browser history remains the most appropriate.
