End user is on a cisco telepresence session with remote participant and can control the camera at the remote endpoint. Which feature is underlying?
The correct answer is A. FECC. Far End Camera Control (FECC) is the feature that allows a local endpoint to send pan, tilt, and zoom commands to control the camera at a remote endpoint during a video call.

Why each option
Far End Camera Control (FECC) is the feature that allows a local endpoint to send pan, tilt, and zoom commands to control the camera at a remote endpoint during a video call.
FECC is defined in the H.281 standard and is supported over H.323 and SIP video calls, allowing participants to remotely control the PTZ (pan-tilt-zoom) capabilities of the far-end camera. When enabled on both endpoints, one participant can adjust the remote camera angle without any manual intervention at the far site, which is the exact behavior described in the question.
DTMF (Dual-Tone Multi-Frequency) transmits touch-tone digit signals used for IVR interaction and has no role in controlling remote cameras.
FEC (Forward Error Correction) is a packet-level technique to recover from media stream loss or corruption and has no relationship to camera control.
PIP (Picture-in-Picture) overlays a smaller self-view or content window onto the main video display but does not provide any mechanism to control a remote camera.
