Under which act is the governmental agency referred to for physical therapy corporations?

The Moscone-Knox Professional Corporation Act is the correct choice because it specifically governs the formation and operation of professional corporations, including those for physical therapy in California. This act provides the legal framework that allows licensed professionals, such as physical therapists, to form corporations while adhering to the regulations and ethical considerations outlined within the act.

Under the Moscone-Knox Act, physical therapy corporations must function in a way that prioritizes the professional standards and responsibilities of the licensed practitioners involved. It addresses issues such as ownership, management, and the provision of services, ensuring that the practice of physical therapy maintains its integrity and professionalism.

The other options, while relevant to different aspects of business law and various practices, do not specifically address the governance or regulatory requirements applicable to physical therapy corporations. The Health and Safety Code, for instance, covers public health matters, while the California Business Corporation Act provides general regulations for all types of corporations, and the Corporate Practice of Medicine Act pertains to the practice of medicine more generally, not specifically to physical therapy as a healthcare profession.
