• C. The film's musical score.
• D. Dialogue clarity

Answer: (B)

Ambient sound is the background audio that surrounds the characters—the ordinary noises that aren’t the main dialogue or music. Its significance lies in giving the scene a sense of place, time, and atmosphere. By including traffic, wind, room hum, distant chatter, or birdsong, it makes the environment feel real and helps the audience understand where and when the action is taking place. It also shapes mood: a bustling city soundscape can feel energetic, while a quiet room’s subtle hum can create intimacy or tension.

The best choice is the one that describes ambient sound as background noise that helps establish the setting, because that is exactly what ambient sound does in film and TV drama. Silence can be used deliberately for effect, but ambient sound’s typical role is to fill the scene with environmental cues that ground the viewer in the location.
