Which factor would likely exacerbate the noise/distraction barrier?

The choice indicating external interruptions and distractions is correct because these elements directly interfere with effective communication. Noise in this context refers to anything that disrupts the clarity of the message being conveyed. When there are external interruptions—like loud sounds, conversations, or visual distractions—participants in the communication process may struggle to pay attention or may misinterpret the information being shared.

A clear and focused message, a quiet and organized environment, and an attentive audience all contribute positively to communication by minimizing barriers. When the communication context is ideal, these factors help ensure that the intended message is understood as the speaker intended. In contrast, external interruptions create a chaotic environment that makes it difficult for individuals to concentrate on the message, thus exacerbating the noise/distraction barrier.
