Vitamins A and C, along with zinc, play a crucial role in the wound healing process. Vitamin A is essential for epithelialization and helps maintain the integrity of mucosal surfaces, which is vital for effective healing. It also aids in the inflammatory response and collagen synthesis, two key phases in the healing process.

Vitamin C is well-known for its role in collagen synthesis, an essential component of the extracellular matrix that provides structure to tissues being repaired. It also has antioxidant properties that protect cells from damage, supporting overall healing.

Zinc contributes to multiple aspects of wound healing, including collagen synthesis, immune function, and protein synthesis. A deficiency in zinc can significantly delay wound healing and increase the risk of infection.

In contrast, other vitamins and minerals mentioned in the other options, such as those in group B, C, and D, do not play the same pivotal roles in the wound healing process as vitamins A and C and zinc. While they are important for overall health, their specific contributions to wound healing are not as pronounced.
