 Explanation: 
Detailed explanation-1: -Complete answer: During transport, diffusion does not require any energy.
Detailed explanation-2: -Diffusion expends no energy. Rather the different concentrations of materials in different areas are a form of potential energy, and diffusion is the dissipation of that potential energy as materials move down their concentration gradients, from high to low.
Detailed explanation-3: -Facilitated diffusion is a passive process: the solutes move down their concentration gradient and do not require the expenditure of cellular energy for this process.
Detailed explanation-4: -So, the correct option is ‘Active transport’.
