Show answer & explanation
Correct answer: D
Standard USB and HDMI ports are designed for specific types of connections. USB ports connect devices like keyboards, mice, and storage drives using USB connectors. HDMI ports transmit video and audio signals to displays or projectors. Ethernet cables, however, use RJ45 connectors designed for network ports (LAN). Because the physical connector shapes and signal protocols differ, an Ethernet cable cannot be plugged directly into a USB or HDMI port without an intermediate adapter.
