Answer:
a. semi-autonomous

Semi autonomous has a dictionary meaning that states being independent to some defined extent.
In the given instance also Devon thinks that her colleagues or coworkers are somewhere between the two categories, that is up to a certain extent they are really independent in their views. While on the other hand, at some situations their views depend on the things like views of coworkers.
Thus, using the term that the coworkers are semi autonomous is correct as to the concern they can exercise their own powers in half way.
