Answer:
B) inside director
Step-by-step explanation:
An inside director is a member of the board of directors that is also an employee of the company. Usually inside directors should be part of the top management of the company, but in some particular cases that may not apply (e.g. in European cooperatives unions are represented by one member in the board).
It doesn't matter if the directors are inside or outside directors (don't work in the company), they all have a duty of care to the company.
