Which of the following terms refers to a small video monitor attached to a camera?

The term that refers to a small video monitor attached to a camera is the viewfinder. The viewfinder is an essential component of camera operation as it allows the operator to frame the shot and see exactly what will be captured by the camera. In digital cameras, especially in video production, electronic viewfinders provide real-time playback of the image sensor, offering an accurate representation of exposure, focus, and composition.

The lens is used for capturing images through focusing light onto the camera's sensor, but it does not function as a monitor. The camera body houses all the mechanical and electronic components but does not relate specifically to the monitoring aspect. The tripod is a stabilizing device for the camera but also does not interact with the visual playback or framing in the same manner as the viewfinder. Therefore, the viewfinder is the correct term for a small video monitor attached to a camera, directly facilitating the videographer's ability to compose shots effectively.
