Answer
A. Red blood cells
Explanation
## Step 1: Hemoglobin is a protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. ## Step 2: Hemoglobin is composed of four protein chains, two alpha chains, and two beta chains, each with a ring-like heme group containing one iron atom. ## Step 3: The iron atoms in the heme group have the ability to bind to oxygen molecules in the lungs and carry them to the tissues where they are used. ## Step 4: Therefore, iron, whose chemical symbol is Fe, is a critically essential mineral for hemoglobin. ## Step 5: Hemoglobin is not found in blood plasma, white blood cells, or lymphocytes. It is specifically located in red blood cells.
