Final answer:
The Office for Civil Rights (OCR) is responsible for administering the Security Rule of HIPAA. The OCR handles the enforcement of HIPAA's Privacy and Security Rules.
Step-by-step explanation:
The organization that has the authority to administer the Security Rule of the Health Insurance Portability and Accountability Act (HIPAA) is the Office for Civil Rights (OCR) which is a part of the U.S. Department of Health & Human Services (HHS). The Security Rule of HIPAA was designed to protect the privacy and security of certain health information. To answer the question, the correct option is (d) OCR.
The Centers for Medicare & Medicaid Services (CMS) oversee parts of HIPAA related to transactions and code sets and the National Provider Identifier, while the FDA regulates food and drugs, and the CDC focuses on public health. The OCR, however, is specifically charged with enforcing the HIPAA Privacy and Security Rules and handling complaints about potential HIPAA violations.
