Answer: Extreme Close Up
Explanation:
In filmmaking, a shot can be first characterized by the camera distance, which refers to the distance of the subject from the camera. An extreme close-up (XCU) shows a small area or detail of the body, which helps to emphasize something like a subject's mouth injury.
On the other hand, a long shot (LG) shows a subject´s whole body, so it would be the worst possible choice for this shot.
