  B. Editors and researchers
  C. The World Wide Web Consortium
  D. The top sites requested by metasearch engines

Directories are compiled and maintained by humans, editors and researchers. A is incorrect because search engines use robots and spiders (automated programs) to search the Web. C is incorrect because the World Wide Web Consortium sets protocol for the Web and does not supply data to directories.

  The correct answer is C.
The World Wide Web provides the vast majority of directory and search engine entries.

D is incorrect because directories and search engines that you access through your browser do not search WAIS entries; WAIS servers use a special query language.
