I think the correct answer from the choices listed above is option C. Cells in multicellular organisms differentiate as they continue to divide and increase in size because cells will now perform special functions and have become different to other cells. Hope this answers the question.
-Cells in multicellular organisms differentiate as they continue to divide and increase in size because cells will now perform special functions and have become different to other cells.
-Cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type. Most types of animal cells differentiate at an early stage. They become specialized for a particular function and cannot change into different types of cells. In mature animals, cell division is mainly restricted to replacement and repair.
