Both A & B
Passive transport requires no energy from the cell. Examples include the diffusion of oxygen and carbon dioxide, osmosis of water, and facilitated diffusion.
Correct option is A)
An input of energy is required in the process of active transport as it involves the movement of ions or molecules across a cell membrane from low to high concentration. The movement requires energy to maintain the electrochemical gradient.
So, the correct option is 'Active transport'.
