Answer options

1. Retinol acetate
2. Methyluracil
3. Retabolil
4. Prednisolone
5. Levamisole

Explanation

Vitamin A (Retinol acetate) is arguably the most important vitamin for effective wound healing due to its role in a process called cellular differentiation. Cellular differentiation is how cells reproduce, which is important for the growth of new blood vessels and tissue structures. Vitamin A can also improve the immune system and lower the risk of harmful infections.
