What form of communication provides the greatest information richness, which is the amount of verbal and non-verbal information that a communication channel carries?

Correct Answer: Option B — One-on-one, face-to-face

One-on-one, face-to-face communication offers the highest information richness because it captures both verbal cues and non-verbal signals like body language and tone. This immediate feedback loop minimizes ambiguity, making it the most effective channel for sensitive discussions or complex instructions where clarity is paramount for safe operations.
