The red blood cells have proteins, hemoglobin and myoglobin, that are responsible for the storage of oxygen from the lungs and transporting it through the body. When the hemoglobin and myoglobin are low, it is because the iron levels are low. When this occurs, the blood, which carries the oxygen, reduces the ability to process its work. When this occurs, anemia, a condition that may cause chest pain, tiredness, and headaches.
I'd say D because it is always good to have a goal for that, and if you plan it out, you have a better chance of reaching it.
