Correct Answer: A

Rationale: The primary reason for giving iron supplementation to pregnant women is to prevent anemia. Anemia can have detrimental effects on both the mother and the developing fetus. Iron is essential for the production of red blood cells, and during pregnancy, the demand for iron increases to support the mother's increased blood volume and the developing fetus. Anemia in pregnancy can lead to complications such as preterm birth, low birth weight, and even maternal mortality.
Therefore, ensuring adequate iron intake through supplementation is crucial to prevent these adverse outcomes.
