Answer:
B. The OSHA inspector must produce a search warrant to enter the unit.
Step-by-step explanation:
Since the manager refuses the officer to carry out his operation, the legal thing to do is to produce a search warrant.
A search warrant is a document signed by a judge that allows a police officer to search for specific items at a particular place and time. And officers can even seize any contraband or evidence of crime that they find while executing a warrant, even if the object isn't mentioned in the warrant.
