Answer: Option A) simple diffusion

Explanation:

Simple diffusion involves the movement of solutes molecules across the plasma membrane along concentration gradient (from high to low region). Unlike active methods of moving molecules, simple diffusion does not require energy (ATP) neither does it require a transport protein.

Thus, simple diffusion is NOT an active method where molecules pass across the plasma membrane
