Answer:
A. formal
Explanation:
Jen's production department is a formal group because relations within the group are governed by official rules, contracts, policies, and are under the legitimate authority of a manager, within the context of a business organization.
Because the department where Jen belongs to is formal, she has to comply the obligations that the authority of the deparment (her boss) imposes on her. If the department was informal instead, Jen could opt out of the obligations if she wished.
