This file includes directives that tell crawling bots whether they are allowed or disallowed from certain directories or pages. For example, if a website owner wants to keep certain sensitive areas or duplicate content from being crawled, they can explicitly mention that in the "robots.txt" file, effectively "inhibiting" the crawlers from accessing that content.

In contrast, the other options do not effectively prevent web spiders from crawling a site. Using site: commands is a search engine query method that does not inhibit crawling, but rather, allows you to search for specific pages indexed by search engines. Minimizing website content does not prevent crawlers from accessing the site but may reduce the total number of pages crawled. Enhancing site security features, while important for protecting data, does not specifically prevent web spiders from
