Answer :
Final answer:
Search engines like Ask.com, Bing.com, and Yahoo.com provide search results from the entire internet. Tumblr.com, despite having a search function for its own content, does not index or retrieve information from the general internet, thus it is not a search engine.
Explanation:
The following options are all types of search engines: Ask.com, Bing.com, and Yahoo.com. They allow users to input search queries, then the search engine will display results related to the query.
However, Tumblr.com is not a search engine as defined by this standard. It's a social networking and microblogging site where users can post and share content. Although users can search for posts or hashtags within Tumblr, it does not gather or index information from the general internet like other search engines.
