Step-by-step explanation:
As per the general rules of corporate liability, a professional corporation is a separate legal entity, and shareholders are not personally liable for the corporation's obligations or actions, including malpractice. Therefore, George can sue only Dr. Inc., and not Eric, Becky, or Brenda individually, for the damages caused by Eric's malpractice. The liability of the corporation is limited to its assets, and the personal assets of the shareholders are protected from creditors' claims in most cases. However, there may be some exceptions to this general rule, depending on the specific circumstances of the case and the state laws governing professional corporations.
