The subject of the question is Health. The student is asking about a specific entity that amended the definition of a Certified Nursing Assistant (CNA) to include individuals who provide services through an agency or under a contract with the facility.
The correct answer is OBRA (b). OBRA stands for the Omnibus Budget Reconciliation Act, which is a federal law that among other things, establishes the requirements for certified nursing assistants.
OBRA regulates the training and certification of CNAs and sets standards of care for nursing homes and other long-term care facilities. The amendment mentioned in the question expanded the definition of a CNA to include those who provide services through an agency or under a contract with the facility.
