The answer is b. relational dimension
The content dimension of communication refers to the literal information or message that is being communicated. In this case, "thanks a lot" could be interpreted as a straightforward expression of gratitude. However, Yolanda's interpretation goes beyond the literal content.
The relational dimension of communication involves the context and the relationship between the communicators, which can influence how a message is interpreted. Yolanda's negative interpretation of "thanks a lot" suggests that she is considering the relational context, possibly perceiving sarcasm or a negative tone based on her relationship with the co-worker.
Noise refers to any interference that distorts or interrupts the message being communicated. While noise can affect interpretation, it does not specifically address the relational aspect of Yolanda's interpretation.
This principle suggests that communication can occur without the sender's intention. However, the scenario provided does not indicate whether the co-worker's comment was intentional or unintentional, making this option less relevant.
This principle means that once a message is communicated, it cannot be taken back. While true, it does not directly explain why Yolanda interprets the comment negatively.
Therefore, the most appropriate answer is the relational dimension, as it best explains Yolanda's interpretation based on the context and relationship with her co-worker.
