Answer:
D. Call an all staff meeting and give everyone the news at once.
Step-by-step explanation:
Instead of letting the rumors spread throughout the company, what Ben is supposed to do is have a meeting with his entire staff and let all of them know at once what's going on. This way, he will be clear and direct and won't allow for gossip to spread throughout his company and he himself will address the issue head-on. This way he won't leave room for misinterpretation as he will explain what is going to happen.
