Final answer:
Correct answer is 4) .Apple's Bonjour technology is designed for automatic discovery of services and network-enabled devices on local networks, distinct from other wireless communication technologies like Bluetooth, Wi-Fi, or NFC.
Step-by-step explanation:
The technology developed by Apple that allows for automatic discovery of services and network-enabled devices on a local network is Bonjour. This service enables devices to automatically find each other without the need to enter IP addresses or configure DNS servers. It's commonly used for file sharing, network printing, and to play music across network devices among other functionalities. While technologies like Bluetooth, Wi-Fi, and NFC enable wireless communications, they do not automatically discover devices and services in the same way Bonjour does.
