Answer:
E) Increased noise
Step-by-step explanation:
The answer is that the condition that would necessitate the use of non-verbal communication instead of verbal communication is increased noise because the noise is any type of sound that affects the verbal communication and in a case of increased noise, it could be necessary to use non-verbal communication to be able to deliver a message.
The other options are not right because they don't affect the verbal communication in a way that forces you to use non-verbal communication.
