Which protocol suite forms the backbone of Internet communications?

Explanation:
The fundamental idea being tested is that global Internet communication relies on a universal protocol stack that enables different networks to connect and exchange data. TCP/IP provides that framework. IP handles addressing and routing so every packet finds its way to the right destination across diverse networks. TCP sits on top of IP to ensure reliable, ordered delivery, managing connections, retransmissions, and data integrity. Together, they form the backbone of how data moves end-to-end across the Internet, supporting higher-level protocols like HTTP, DNS, and email. The other options represent technologies used for local or short-range networks. ZigBee is designed for low-power, wireless sensor networks; Wi‑Fi provides wireless access within a local area but uses TCP/IP on top of it rather than forming the global routing backbone; Bluetooth is for short-range device-to-device communication. While these technologies may carry Internet traffic, they do not by themselves establish the universal framework that underpins Internet-wide communication.
