**Core Concept:** Rashtriya Swasthya Bima Yojna (RSBY) is a social health insurance scheme in India aimed at providing financial assistance to low-income families for healthcare expenses. It was launched as part of the National Rural Health Mission (NRHM) in 2008.

**Why the Correct Answer is Right:** RSBY is under the Ministry of Health and Family Welfare (MOHFW). This ministry is responsible for overseeing healthcare policies and initiatives in India, including the NRHM. The scheme was initiated to improve access to healthcare services for the underprivileged sections of the population.

**Why Each Wrong Option is Incorrect:**
A. Ministry of Communications (MoC): This ministry is concerned with telecommunications and infrastructure development, not healthcare.
B. Ministry of Labour and Employment (MoLE): Although this ministry deals with labor-related issues, it is not responsible for healthcare policies.
C. Ministry of Steel (MoS): This ministry deals with iron and steel production and is unrelated to healthcare.
D. Ministry of Social Justice and Empowerment (MoSJE): This ministry focuses on social welfare and disability-related issues, not healthcare.

**Clinical Pearl:** Understanding the administrative structure of healthcare initiatives in India is crucial for understanding their implementation and effectiveness. This knowledge can help students appreciate the interplay between different ministries and their roles in public health policies.
