Answer:
The correct answer is letter "B": Enable opportunity teams and allow users to add the product manager.
Step-by-step explanation:
The situation portraits a gap between salespeople and product managers. Salespeople need assistance when selling certain products but product managers do not have access to those opportunities. In that case, a system administrator must link the two parties by enabling opportunity teams. Then, salespeople directly can add a product manager to the opportunity team according to the type of assistance needed.
