________ means made or constructed of an absorbent material.

• A. Durable
• B. Porous
• C. Non-porous
• D. Rigid

Answer: (B)

Porous means made or constructed of an absorbent material. Materials with pores have tiny openings that allow liquids to be absorbed and held within the fabric or substance. In a salon sanitation context, porous items like cotton towels, sponges, or certain woods can soak up moisture and contaminants; liquids can penetrate into the fibers, making thorough disinfection harder and increasing the risk of cross-contamination. That’s why non-porous surfaces and tools are preferred for areas and items that must be cleaned and disinfected regularly. The other terms describe different properties: durable refers to how long something lasts under use, non-porous means not absorbing liquids, and rigid describes stiffness rather than absorbency.
