**Core Concept**
The Baby-Friendly Hospital Initiative (BFHI) is a global program launched by the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) to promote and support breastfeeding-friendly practices in hospitals. This initiative is based on the Ten Steps to Successful Breastfeeding, which aim to support mothers in initiating and maintaining breastfeeding.

**Why the Correct Answer is Right**
The BFHI was launched to address the issue of suboptimal breastfeeding rates worldwide. The initiative emphasizes the importance of hospital practices that support breastfeeding, such as skin-to-skin contact, rooming-in, and exclusive breastfeeding. The Ten Steps to Successful Breastfeeding serve as a framework for hospitals to assess and improve their breastfeeding policies and practices.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the BFHI is not launched by the American Academy of Pediatrics (AAP). While the AAP provides guidelines and support for breastfeeding, it is not the primary organization behind the BFHI.
**Option B:** This option is incorrect because the BFHI is not launched by the World Medical Association (WMA). The WMA is an international organization that promotes medical ethics and human rights, but it is not directly involved in the BFHI.
**Option C:** This option is incorrect because the BFHI is not launched by the American College of Obstetricians and Gynecologists (ACOG). ACOG provides guidelines and support for obstetric care, but it is not the primary organization behind the BFHI.

**Clinical Pearl / High-Yield Fact**
The BFHI is a key initiative in promoting breastfeeding worldwide, and hospitals that adopt the Ten Steps to Successful Breastfeeding have been shown to have higher breastfeeding rates and better maternal and infant health outcomes.

**Correct Answer:** D. The World Health Organization (WHO) and the United Nations Children's Fund (UNICEF).
