Step-by-step explanation:
The example of a two-shot from the options provided would be B) Two political commentators discussing a presidential debate. A two-shot is a type of camera shot in film or television where two subjects are captured within the same frame. This setup is often used to showcase an interaction between the two subjects, like a conversation or an interview. While it may be tempting to consider option D) A reporter interviewing two subjects at the same time, it's not specified that they are both captured within the same frame, which is a requirement for a shot to qualify as a two-shot.
