The correct answer is Wi-Fi connectivity. This allows the iPhone to communicate wirelessly with macOS devices, enabling features such as continuity camera, where the iPhone can act as a webcam for the Mac. This seamless integration leverages Wi-Fi, specifically allowing for high-quality video transmission without the need for physical connections, making it convenient and flexible for users.

Wi-Fi connectivity allows not only for video streaming but also facilitates high-bandwidth requirements necessary for high-resolution video, which is crucial for a webcam function. In contrast, USB connectivity does provide a direct connection but does not offer the same level of flexibility as wireless options. Bluetooth typically has a limited range and lower data transfer speeds, making it unsuitable for high-quality video transmission. Ethernet requires a wired network connection and is not applicable for direct device-to-device communication like that between an iPhone and a Mac in this context.
