Question

The type of communication that the teacher has in the classroom, is termed as
a. Interpersonal
b. Mass communication
c. Group communication
d. Face-to-face communication

Answer 1

It's definitely not a mass communication: it does not include mass media.

It's actually all the other choices:

a. Interpersonal (between people)
c. Group communication (in a group)
d. Face-to-face communication (not mediated by technology)

I would choose the option of Group communication, as it's its more visible trait, but technically, all those options are correct!
