The most accurate answer is C.
The cytoskeleton is responsible for cell shape, motility (movement) and motility of organelles within a cell.
Unlike the human skeleton , the cytoskeleton is extremely dynamic, meaning the filaments that make up the cytoskeleton are able to shorten or lengthen very rapidly.
This dynamic nature is necessary for cells to be able to change shape, complete cell division, or migrate (move from one place to another).The cytoskeleton connects to every organelle and every part of the cell membrane.
