Explanation
A webcam is the essential device for video conferencing because it captures live video of the user and transmits it to the remote participant. While a microphone handles audio (also important), the question specifically asks about enabling video conference calls, which requires video capture hardware. A digitizer converts analog drawings to digital input (used for graphic tablets), and an LCD display is an output device - neither provides the video input necessary for video calling.
