What leadership role and style best describes Hassan? A. instrumental role and authoritarian style B. instrumental role and democratic style C. expressive role and authoritarian style D. expressive role and democratic style

The correct answer is B.

Hassan plays an instrumental role because he takes initiative within his group, which is probably why his group often does the best. Also, he has a democratic style because he takes into account his group members' preferences, rather than simply making decisions on his own (which would be an authoritarian style).
