**Core Concept**
The Reproductive and Child Health (RCH) program is a comprehensive approach to improving the health and well-being of mothers, children, and families. It encompasses a range of strategies to promote healthy behaviors, prevent illnesses, and provide essential services.

**Why the Correct Answer is Right**
The RCH program has four key components: (1) Maternal Health, which focuses on reducing maternal mortality and morbidity through antenatal care, skilled delivery, and postpartum care; (2) Newborn Health, which prioritizes neonatal care, vaccination, and prevention of infections; (3) Child Health, which emphasizes immunization, nutrition, and management of common childhood illnesses; and (4) Family Planning, which promotes voluntary family planning and reproductive health services to prevent unintended pregnancies and reduce adolescent pregnancies.

**Why Each Wrong Option is Incorrect**
* **Option A:** Not a valid component of RCH.
* **Option B:** Not a correct component of RCH, though it may be related to family planning.
* **Option C:** Not a correct component of RCH, though it may be related to maternal health.
