Biology

The correct answer is: B.It maintains tissue function and homeostasis.

Repairing damaged cells is crucial because it helps maintain the proper function of tissues and ensures homeostasis (the stable internal environment). If cells are damaged and not repaired, the function of organs and tissues can be impaired, leading to malfunction or disease. Cell repair ensures that normal biological processes continue, promoting the survival and health of the organism.

Why the other options are less relevant:

A.It increases genetic diversity: Genetic diversity is mainly achieved through sexual reproduction, not cell repair.
