Final answer:
Face-to-face communication is true to be the richest form according to the media richness theory because it conveys multiple cues and allows for immediate feedback, making it ideal for complex or sensitive conversations.
Step-by-step explanation:
The statement 'Face-to-face communication is at the top of media richness' is true. Media richness theory suggests that communication channels differ in their capacity to convey information and enable understanding. Face-to-face communication is considered the richest form of communication because it allows for immediate feedback, conveys multiple cues such as body language and tone of voice, and facilitates the personal, emotional connection that other forms of communication may lack. Given its richness, face-to-face interaction is generally preferred for complex or sensitive communications that may require nuance and subtlety.
