The correct answer is option 1, Anaemia. Anaemia is a condition characterized by a decrease in the number of red blood cells or a decrease in the amount of hemoglobin in the blood. Iron is an essential component of hemoglobin, the protein in red blood cells responsible for carrying oxygen to tissues throughout the body. When there is a deficiency of iron, the body is unable to produce enough hemoglobin, leading to a decreased ability to transport oxygen. This can result in symptoms such as fatigue, weakness, shortness of breath, and pale skin. It is important to consume foods rich in iron or take iron supplements to prevent and treat iron deficiency anaemia.
