Final answer:
Communicators in high-context cultures rely heavily on environmental cues.
Step-by-step explanation:
The correct statement about the role of culture in communication is C. Communicators in high-context cultures rely heavily on environmental cues.
High-context cultures are those where much of the meaning of communication is conveyed through non-verbal cues, such as body language, facial expressions, and silence. The context and situational factors play a significant role in understanding the intended meaning. Examples of high-context cultures include many Asian and Middle Eastern cultures.
On the other hand, low-context cultures, like many Western cultures, rely more on explicit and direct communication. In these cultures, the emphasis is on the words spoken rather than the non-verbal cues.
