Correct:
D
Explanation
HTTPS (Hypertext Transfer Protocol Secure) is the correct answer as it is specifically designed for secure communication over a computer network. It is an extension of HTTP that uses TLS (Transport Layer Security) or its predecessor, SSL (Secure Sockets Layer), to encrypt the data exchanged between a web browser and a server. This encryption ensures data confidentiality and integrity, protecting against eavesdropping and tampering.
- HTTP: The standard protocol for transferring data, but it transmits information in plain text, making it insecure.
- DHCP: Used for automatically assigning IP addresses to devices on a network.
- SMTP: The standard protocol used for sending emails; while it can be secured (e.g., SMTPS), its primary function is mail transfer, not general secure web communication.
