Answer: A.
Step-by-step explanation:
Strong, dynamic gunshots would suit a scene where a couple crouches near the steps in terror. This type of musical cliche would effectively convey the tension and fear felt by the characters, and effectively enhance the dramatic impact of the scene. The loud, dynamic sound of gunfire would be jarring and would underscore the danger and immediacy of the situation.
In many action or suspense scenes, music plays a crucial role in setting the mood and setting the tone. In this case, the use of gunfire as a musical cliche helps create a sense of danger and urgency, which is especially important in a scene where a couple cower in fear.
