Skin

Explanation:

The tissues with high mitotic index have a number of cells undergoing mitosis. Among the given options, cells of skin exhibit the highest mitotic index. The skin forms the outer most covering of the body surface. Its cells are exposed to various agents of wear and tear.

To replace the damaged cells, the cells of the skin undergo mitosis. So, skin exhibits the highest mitotic index.
