Look at the image below. Where should you click to learn about toxic markers of the first backlink in the list?

Clicking "3" (the "i" icon) next to a specific backlink reveals detailed information about that link, including its toxic markers. This icon is designed to provide granular insights into individual backlinks. Option "1" is a general filter for all backlinks, not a specific link's details. Option "2" is a general "Audit" button, which likely initiates a broader analysis rather than showing details for one link. Option "4" is a column header, used for sorting, not for accessing detailed information.
