Individual user web browsing history is the correct choice because the network diagnostics overview focuses on network and service level metrics rather than per user browsing records.

Network diagnostics dashboards and overviews are designed to show aggregate and technical indicators that help troubleshoot connectivity and performance. By contrast Individual user web browsing history is application layer content and it raises privacy and data access concerns, so it is not typically displayed in a network diagnostics overview.

DNS lookup latency is incorrect because DNS timing is a standard network metric and diagnostics views commonly surface it to help identify name resolution delays.
