Answer: b.) a sequence that cuts back and forth between two characters interacting
Step-by-step explanation: Shot reverse shot (or shot/countershot) is a film technique where one character is shown looking at another character, and then the other character is shown looking back at the first character. Considering the characters are shown facing in opposite directions, audience assumes that they are looking at each other. Continuity editing in film or video production is using shot reverse shot as a framing technique. This makes the viewer feel like he/she is looking at a continuous action. It makes it seem as the scene the audience is watching is happening linearly in real time.
