Analyze the screenshot below, which of the following sets of results will be retrieved using this search?

The search query shown uses the site:sans.edu operator to scope results to that domain combined with a link-based operator, which returns pages hosted on sans.edu that contain external hyperlinks. This is a passive reconnaissance technique used to map a target organization's web relationships and referenced resources.

Returning .php files requires the filetype:php or ext:php operator explicitly paired with site:sans.edu; the query shown does not use a filetype operator.

ext:php and site:sans.edu are functional Google dork directives interpreted by the search engine, not literal text strings; a dork query would not return pages simply containing those character sequences as plain text.

The link: operator identifies pages that reference a domain via hyperlinks, not HTTP redirect behavior; redirect filtering is not a function of standard Google search operators.
