Show answer & explanation
Correct answer: A
To solve this, we match each technology to its specific use case and range. First, connecting a smartwatch or wireless headphones to a phone is typically done using Bluetooth (E), which operates over a short range (A). Second, connecting devices to the Internet locally using radio waves for high-speed data transfer over short distances refers to Wi-Fi (C). Finally, connecting the phone to services via the Internet using cellular networks involves 3G/4G/5G (D), which covers a long range (B). Therefore, the correct sequence is Bluetooth, Short, Wi-Fi, 3G/4G/5G, Long.
