Correct option is A
The correct answer is: (a) Telnet
Explanation:
Telnet is a network protocol used to access remote computers over the internet or local networks. It is not a web browser; it is used for command-line communication and accessing servers remotely.
Google Chrome, Mozilla Firefox, and Microsoft Edge are all popular web browsers used to access and browse websites on the internet.
Therefore, Telnet is not a web browser.
