**Core Concept**
Janani Suraksha Yojana (JSY) is a safe motherhood intervention under the National Rural Health Mission (NRHM) aimed at reducing maternal and neonatal mortality by promoting institutional delivery among poor pregnant women. The program focuses on improving access to institutional delivery services for disadvantaged groups.

**Why the Correct Answer is Right**
The JSY scheme targets low-performing states with low institutional delivery rates, particularly those with poor maternal and child health indicators. By providing financial incentives to pregnant women from these states, the program aims to encourage them to deliver in healthcare facilities, thereby reducing maternal and neonatal mortality. The program's focus on low-performing states is crucial in addressing the disparities in healthcare access and outcomes.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as JSY is not restricted to a specific income group, but rather focuses on promoting institutional delivery among poor pregnant women.
**Option B:** This option is incorrect as JSY is not limited to high-performing states, but rather targets low-performing states with poor healthcare indicators.
**Option C:** This option is incorrect as JSY is not focused on promoting family planning services, but rather aims to reduce maternal and neonatal mortality through institutional delivery.

**Clinical Pearl / High-Yield Fact**
Janani Suraksha Yojana is a key initiative in reducing maternal and neonatal mortality in India, particularly in low-performing states. It highlights the importance of targeted interventions in improving healthcare access and outcomes for disadvantaged groups.

**Correct Answer: C.**
