Which one of the following Google advanced search operators allows an attacker to restrict the results to those websites in the given domain?

The [cache:] operator retrieves Google's cached snapshot of a specific URL and does not filter results by domain.

The [site:] operator instructs Google to return only results from a specific domain or subdomain (e.g., site:example.com). Attackers use this during the reconnaissance phase to enumerate publicly indexed pages, subdomains, and sensitive files belonging to a target organization without directly interacting with its infrastructure.

The [inurl:] operator searches for a keyword within URLs but does not restrict results exclusively to a single domain.

The [link:] operator finds pages that link to a specified URL and is not used to scope results to a target domain.
