Which is the last step in skin repair?

A. the sweat glands released their product, causing the hair to grow
Hair does not grow postmortem, and sweat gland activity ceases after death.

B. the skin retracted from the hair follicles
After death, the skin dehydrates and shrinks, which can cause the hair shaft to appear longer, giving the illusion that hair has grown, even though it hasn't.

C. during the process of decomposition, the hairs grew out of the follicles
Hair cannot grow after death because cellular metabolism and mitosis cease.

D. the skin grew out, forcing the hair out of the follicles
Skin does not grow postmortem; this is scientifically inaccurate.

A. edema
Edema involves fluid accumulation and can contribute to swelling and immune cell movement, but it does not directly wall off the injury site.

B. vasodilation of blood vessels
Vasodilation increases blood flow to bring immune cells and nutrients, but does not physically isolate the injury.

C. formation of a clot
A blood clot forms a physical barrier that helps prevent the spread of pathogens and walls off the injury.

D. all of the above
While A and B support inflammation and healing, only C directly achieves the goal of physically walling off the injured area. Therefore, "all of the above" is in
