Step-by-step explanation:
A sequence of frames or panels that depict a TV commercial in still form is called a storyboard. A storyboard is used to plan out the visual and narrative flow of the piece, which may include aspects like blocking, transitions, and the succession of stage pictures.
Directors and creatives rely on storyboards to ensure that their choices effectively address the needs of their audience and to visually represent the sequence of a narrative, whether for TV commercials, films, or other media projects.
Storyboarding allows creators to think critically about what genre and visual elements, such as photo essays with captions, will best tell their story and evoke the intended emotional responses from viewers. So Option C.
