Answer:
The correct answer is - low permeability.
Explanation:
Low permeability does not allow the pollutant to leak or diffuse from the pollutant to the ocean or aquifers near landfills. The permeability of protective material should be lower as they lead the pollutants to the soil, and environment such as contents of battery, toxic plastic, and other pollutant toxins to the soil and aquifers.
Thus, the correct answer is - low permeability.
