The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Context**: The question asks about the mineral found in the red pigment of vertebrate blood. The red pigment is primarily associated with red blood cells. 2. **Understand the Composition of Red Blood Cells**: Red blood cells (RBCs), also known as erythrocytes, contain a specific protein that gives them their red color. 3. **Identify the Red Pigment**: The red pigment in vertebrate blood is known as hemoglobin. Hemoglobin is a quaternary protein composed of four polypeptide chains. 4. **Structure of Hemoglobin**: Hemoglobin consists of two alpha chains and two beta chains. These chains are essential for the molecule's function in transporting gases. 5. **Identify the Mineral Component**: Within the hemoglobin structure, there is a central atom that plays a crucial role in its function. This central atom is a mineral. 6. **Determine the Mineral**: The mineral found at the center of the hemoglobin molecule is iron (Fe). Iron is essential for the binding and transport of oxygen and carbon dioxide in the blood. 7. **Conclusion**: Based on the analysis, the mineral found in the red pigment of vertebrate blood is iron. **Final Answer**: The mineral found in the red pigment of vertebrate blood is **iron**. ---
