**Question:** MDG is to reduce MMR by

A. using antibiotics
B. promoting breastfeeding
C. increasing awareness about vaccination
D. reducing neonatal infections

**Core Concept:** The Millennium Development Goals (MDGs) were a set of eight global targets established by the United Nations in 2000 to address extreme poverty and other significant global issues. One of the MDGs was to reduce maternal mortality ratio (MMR), which is the number of maternal deaths per 100,000 live births.

**Why the Correct Answer is Right:** The correct answer is B, promoting breastfeeding, because breastfeeding has several benefits for both mothers and babies, which contribute to reducing maternal mortality. Breast milk provides essential nutrients, antibodies, and immunological protection for infants, reducing the risk of infections and related complications.

**Why Each Wrong Option is Incorrect:**

A. Using antibiotics (option A) is not directly related to reducing MMR. While antibiotics can help treat infections, they are not a strategy for preventing maternal deaths.

C. Increasing awareness about vaccination (option C) is important for promoting maternal health, but promoting breastfeeding has a more direct and significant impact on reducing MMR.

D. Reducing neonatal infections (option D) is relevant to maternal health, but promoting breastfeeding addresses the risk of maternal mortality more directly, as breastfeeding reduces the risk of severe infections and related complications.

**Clinical Pearl:** The MDGs have since been succeeded by the Sustainable Development Goals (SDGs), but the importance of promoting breastfeeding remains significant for maternal health worldwide, including reducing MMR and improving overall child health.

**Correct Answer:** B. Promoting breastfeeding.
