The cytoskeleton in a cell is responsible for various functions, including providing structural support, facilitating cell motility, and participating in intracellular transport. It consists of protein filaments and tubules that give the cell its shape and are involved in movement within the cell and cell motility as a whole.
So, the correct option is (B): Motility
