The correct syntax to disallow indexing of files with a specific extension, in this case, PowerPoint files (.ppt), is to use "Disallow: /*.ppt$" in the robots.txt file. The "$" symbol at the end specifies that the rule applies to URLs ending with ".ppt", thus the correct answer is the extension "ppt" without the dollar sign.
