Final answer:
The true statement about laws and regulations in physical therapy is that licensing requirements vary by state within the U.S., reflecting individual state governance.
Step-by-step explanation:
The statement that is true regarding laws and regulations governing physical therapy practice is: C) Licensing requirements for physical therapy practice vary from state to state within the United States. Each state has its own regulatory body that defines laws and requires licensing for physical therapists and physical therapist assistants. This is because healthcare regulations, including those for physical therapy, are largely determined at the state level, not the federal level. Thus, a physical therapist must be aware of and comply with the specific laws and licensing requirements in the state where they practice.
