Which term means not permitting penetration or passage?

• A. Hygiene
• B. Impaired
• C. Incidence
• D. Impervious

Answer: (D)

Not permitting penetration or passage is described by impervious. This word indicates something acts as a barrier that liquids, gases, or other substances cannot pass through, or that a surface resists penetration. In practical use, an impervious material or barrier stops what tries to get through, like a waterproof seal or protective glove. Hygiene relates to cleanliness and infection prevention, not a barrier to passage. Impaired means not functioning or damaged, while incidence refers to the rate at which something occurs. So impervious is the best fit because it directly conveys resistance to penetration.
