Solution
The correct option is C ATP
Active transport, which is the movement of ions or molecules across a cell membrane in the direction opposite that of diffusion, that is, from an area of lower concentration to one of higher concentration, requires the assistance of a type of protein called a carrier protein, using energy supplied by ATP. So, the correct option is 'ATP'.
