**Core Concept**
Pradhan Mantra Swasthya Suraksha Yojana (PMSSY) is a government initiative under the Ministry of Health and Family Welfare, aimed at strengthening primary health care by enhancing the capacity of rural health centers through infrastructure development and human resource training.

**Why the Correct Answer is Right**
PMSSY was launched in **2006** as a key component of the National Health Mission to improve access to quality healthcare in rural India. It focuses on upgrading primary health centers (PHCs), providing better infrastructure, equipment, and trained personnel. The scheme emphasizes preventive care, early diagnosis, and community-based health services, aligning with the broader goals of the National Rural Health Mission (NRHM).

**Why Each Wrong Option is Incorrect**
Option A: 2003 – This is incorrect because the National Rural Health Mission (NRHM) was launched in 2005, and PMSSY was introduced later as a focused initiative under it.
Option C: 2007 – This is incorrect as no major national health scheme named PMSSY was launched in 2007; the timeline does not match official records.
Option D: 2008 – This is incorrect because PMSSY was not launched in 2008; it was introduced earlier in the health policy framework.

**Clinical Pearl / High-Yield Fact**
PMSSY is a cornerstone of rural health strengthening in India, ensuring that PHCs are equipped with essential services and staffed with skilled personnel—key to achieving equitable health outcomes in underserved areas.
