Answer:
d. Film the scene so that most is in darkness, but illuminate only the faces of the two characters so that we know the characters' identities.
Step-by-step explanation:
This would be the best way to film such a scene. In this example, the lightning is partially responsible for conveying to the viewer the mood that the director wants to achieve. If the story follows a stalker and his victim, the mood would most likely be one of suspense or fear. This would be better achieved in a dark setting. However, the scene should not be so dark that it makes it impossible for the viewer to know the identities of the characters.
