Which of the following must be declared by any nonpublic corporation owning a retail drug outlet?

In the context of a nonpublic corporation that owns a retail drug outlet, declaring the owners of 5% or more stock is essential for regulatory and oversight purposes. This requirement ensures transparency regarding the stakeholders who have a significant ownership interest in the corporation. Knowing who holds substantial shares can help regulatory bodies assess potential conflicts of interest and ensure that those individuals meet necessary professional standards, which is crucial in the management and operation of a retail drug outlet that handles pharmaceuticals.

This information plays a vital role in maintaining the integrity of the pharmacy practice and ensuring that those in control of the operation adhere to the regulatory requirements surrounding pharmaceutical distribution and safety. Thus, the emphasis on declaring shareholders who own 5% or more stock reflects the state's recognition of their influence and responsibility within the framework of public health and safety. The other options, while they relate to the personnel or employees associated with the retail outlet, do not carry the same significance in terms of ownership disclosure and regulatory scrutiny.
