After working hard and earning honors during his first year in a difficult engineering program, andrew was awarded the best student in his group. while handing him the certificate, his professor said, "well done," without any enthusiasm, and andrew also noticed the professor didn’t meet his eye. from the professor’s reaction, andrew knew he was not happy with him for some reason. which dimension of communication message is implied by the professor

The correct answer is Relational dimension.

Explanation:

In communication there are two dimensions the actual content of a communication which is the content or the information being explicitly discussed and the other dimension which is the relational dimension which is the part of the communication that is not explicit in it but it's whatever the message communicate about the messenger's feelings towards the other person or the listener. Therefore in Andrew's interaction with the professor we can clearly evidence that the message that the professor gave corresponds to the Relational dimension.
