Answer:
Cells of skin, for instance, have highest mitotic index.
Explanation:
Many cells are capable of dividing rapidly. For example, in plants, the cells near the root tip in the apical meristem divide rapidly to push through the soil because the root cap detects the gravity and direct rapid division and growth of cells near the tip.
If we take muscle, skin, kidney, and lung as examples that are given in real question, skin cells have the highest mitotic index because they need to get replaced most frequently.
