Final answer:
The pharmacy owner must notify the board of a change in PIC.
Step-by-step explanation:
The correct answer is b) The pharmacy owner. The pharmacy owner is responsible for notifying the board of any changes in the Person in Charge (PIC) at the pharmacy. The PIC is the designated individual who is responsible for overseeing the operation of the pharmacy and ensuring compliance with all applicable laws and regulations.
In this case, the pharmacy owner has the responsibility to inform the board if there is a change in the person designated as the PIC. The pharmacy technician and the janitor do not have the authority or responsibility to notify the board of a change in PIC. While the President of the United States is an important figure, they are not involved in the operations of a pharmacy.
