**Core Concept**
The Revised National Tuberculosis Control Programme (RNTCP) is a nationwide initiative in India to control and prevent tuberculosis. The RNTCP has adopted a directly observed treatment, short-course (DOTS) strategy to ensure effective treatment and reduce treatment failure rates.

**Why the Correct Answer is Right**
The RNTCP features a decentralized approach to TB control, with a strong emphasis on community participation and involvement. The program relies on a network of TB units and health workers who provide direct supervision and support to patients undergoing treatment. This approach helps to improve adherence to treatment, reduce default rates, and ultimately, achieve better treatment outcomes.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a feature of the RNTCP. While TB units and health workers play a crucial role in the program, the term "satellite centers" is not a specific feature of the RNTCP.
**Option B:** The RNTCP does not rely solely on "private sector" involvement. While private sector participation is encouraged, the program's success depends on a collaborative effort between government, private sector, and community stakeholders.
**Option C:** The RNTCP's focus is on TB control, not "HIV/AIDS management." While there is some overlap between TB and HIV/AIDS, the RNTCP is specifically designed to address TB.

**Clinical Pearl / High-Yield Fact**
The RNTCP's decentralized approach and emphasis on community participation have helped to increase TB treatment coverage and reduce treatment failure rates in India.

**Correct Answer: D. Public-Private Partnership.**
