Which of the following is an example of film form?

The correct choice highlights the lighting in a scene as an example of film form. In the context of film studies, "film form" refers to the overall structure, technique, and specific elements that contribute to the aesthetic and narrative components of a film. Lighting is essential as it affects the mood, tone, and visual storytelling of a film. It shapes how characters and scenes are perceived and can influence the audience's emotional response.

While the storyline, visual effects, and soundtrack are critical components of a film, they are not as closely aligned with the concept of film form. The storyline relates more to film content and narrative, the visual effects are additional elements that may enhance the film’s impact but occur outside the core framework of film form, and the soundtrack, while vital for atmosphere and emotional resonance, does not constitute the structural element of film form itself.
