Answer:
C. IT Group. :)
Step-by-step explanation:

D. Computer customer service does NOT meet with the definition, so we can rule D out of our option choices.
C. IT group CAN meet with the definition, but lets keep looking.
B. IT workers would not meet with the definition. IT workers may create the image of actual workers in the IT club, most perhaps.
A. Computer Science club. Yes, this makes sense. We could choose A.
A or C? C. IT Group would make the most sense. Group and department almost have the same meaning. A department has a group of people in it, so C would be the choice that matches the most. Hope this helps, have an amazing day! :) :)
