Answer:
A and D
Step-by-step explanation:
Your top leader coordinates the activities of functional departments, like the Marketing and Sales department, and customer groups, like Small Business Accounts division.
One matrix boss is in charge of the Small Business Accounts division.
In an organization that has a matrix structure, one matrix boss oversees one side of the matrix, either a functional area (in this case Marketing & Sales) or a division (in this case the Small Business Accounts division).
Top leader is used to describe the manager that coordinates the entire matrix, in this case, both the Small Business Accounts division and the Marketing and Sales department. This manager must resolve competing demands between the two sides of the matrix.
