The type of active transport among the options provided is "engulfing." Engulfing, often referred to as endocytosis, is a process where cells take in substances by engulfing them in a membrane-bound vesicle. Active transport requires energy, typically in the form of ATP, which is necessary for moving substances against their concentration gradient.

The other options—diffusion, osmosis, and effusion—are methods of passive transport and do not require energy.
