Well managed work groups offer several advantages over individual workers. which of the following is not a typical advantages of working in a group?
a. accuracy
b. efficiency
c. productivity
d. enthusiasm

I would say D. enthusiasm. Because you can manage productivity and stuff but you can't manage others emotions

I believe the answer to your question would be D. - Enthusiasm.  I think this because while when you work in a group, you may be productive and stuff, but you make not like the people you work with, so you would not feel enthusiastic.  You cannot make people feel enthusiastic by being around them (I mean you could...but you said not a TYPICAL advantage)
I hope I helped you!
Have a great day!
