Vitamin C is associated with which set of roles?

All of the above Iron absorption Wounds Immune system

Correct Answer:

All of the above

Explanation:

Vitamin C serves multiple roles that affect different aspects of health: it is essential for collagen synthesis, which is needed for the repair and integrity of wounds; it enhances iron absorption by reducing ferric iron (Fe3+) to the more absorbable ferrous form (Fe2+); and it supports the immune system by helping maintain barrier function, aiding immune cell function, and acting as an antioxidant. Because it participates in all three areas—iron uptake, tissue repair, and immune defense—the best choice is the one that encompasses all of these roles. Deficiency in vitamin C leads to poor wound healing and other issues like easier bruising and weakness, illustrating how interconnected these functions are.
