Which of the following nutrients is essential for wound healing?

Vitamin C plays a crucial role in wound healing due to its ability to aid in collagen synthesis, which is vital for the repair of tissues and the formation of new skin. Collagen is a protein that provides structure to skin and connective tissues, and adequate levels of Vitamin C are necessary for stabilizing its structure.

Moreover, Vitamin C has antioxidant properties that help to protect the body from oxidative stress, which can impede the healing process. Additionally, it supports the immune system, which is essential for preventing infections in wounds and facilitating overall recovery. Therefore, adequate intake of Vitamin C is essential for effective wound repair, making it the correct choice in this context.
