Which of the following is not an example of popular web-based search engines?

Answer: Microsoft Edge is not a web-based search engine.

Reason:

• A search engine is a web service that indexes web content and returns relevant results in response to user queries. Examples include Bing, Google, and Yahoo.

• A web browser is software used to access and display web pages. Microsoft Edge is a web browser; it can use search engines to perform searches but does not itself operate as a search engine.

• Therefore, Microsoft Edge is the correct choice for the item that is not an example of a popular web-based search engine.
