Which of the following is NOT a type of permeability?

Explanation:
Permeability describes how easily a membrane lets substances pass. A membrane can be freely permeable, meaning substances cross readily by diffusion; or selectively permeable, meaning only certain molecules can cross depending on size, charge, or transport proteins. Impermeable describes a condition where essentially no passage occurs, which is a description of the absence of permeability rather than a way the membrane allows passage. Active transport, while a crucial process for moving substances across membranes, is an energy‑requiring mechanism and not a permeability category. So imperмeable is the term that isn’t a type of permeability.
