## **Core Concept**
The disciplinary control over Registered Medical Practitioners in India is primarily regulated by a specific act that governs the registration of medical practitioners and maintains a code of conduct for them.

## **Why the Correct Answer is Right**
The Indian Medical Council Act, 1956 (now replaced by the National Medical Commission Act, 2020) was responsible for regulating the medical profession in India, including the disciplinary control over registered medical practitioners.

The NMC has replaced the Medical Council of India (MCI) and is responsible for maintaining the code of conduct and taking disciplinary actions against medical practitioners.
