Answer:
A. Middle managemen
Explanation:
According to my research on different managerial roles, I can say that based on the information provided within the question Boris is part of the middle management. This can be said because Middle Management are under the executive management which in this case are the sales managers and they are many times responsible for junior staff performance and productivity. Since Boris is under the Sales Managers and meets regularly with other managers at his level to most likely talk about managerial problems and solutions we can say that he is Middle Management.
