Show answer & explanation

Correct answer: D

The correct answer is VOIP (Voice over Internet Protocol).

VOIP is the technology that enables voice communication over the Internet, also known as Internet Telephony. It converts voice signals into digital data packets and transmits them over IP networks.

On the other hand, POP3 (Post Office Protocol) and SMTP (Simple Mail Transfer Protocol) are used for receiving and sending emails respectively, while TELNET is used for remote login and command execution on a remote machine. These protocols do not support voice communication.

Therefore, the correct answer is VOIP.
