Step-by-step explanation:
The statement that does not describe a team-based structure is option A, which states that team-based structures have a narrow span of control due to the requirement for close supervision. In reality, team-based structures often have a wider span of control as team members are empowered to make decisions and take responsibility for their work. They work together as self-directed teams, which is described in option B. Option C states that team-based structures have high formalization because teams are given relatively few rules about how to organize their work. This is not true as team-based structures tend to be less formal and allow for flexibility.
