The correct answer to the question is:
OC) differentiation.
Explanation:
1. Differentiation is the process whereby normal cells develop distinct appearances and specialized functions.
2. During differentiation, cells undergo changes in gene expression that allow them to take on specific roles in the body.
3. This process is crucial for the proper functioning of tissues and organs in multicellular organisms.
4. Examples of differentiation include the specialization of stem cells into various cell types like nerve cells, muscle cells, or skin cells.
5. On the other hand, mutation refers to changes in the DNA sequence, dedifferentiation is the loss of specialized features by a cell, and mitosis is the process of cell division.
