Which term describes a liquid that is contaminated?

• A. Rinsate
• B. Dirty
• C. Contaminated
• D. Fresh

Answer: (C)

The main idea is using a precise term to describe a liquid that has unwanted substances. In safety and regulatory language, when a liquid has contaminants, it is described as contaminated. This tells you immediately that the liquid poses a risk and needs proper handling or disposal. Rinsate refers to the liquid produced from rinsing and isn’t inherently labeled as contaminated; it can be contaminated or not depending on what's rinsed. Dirty is informal and not a precise technical term, and fresh means clean, not contaminated. So the exact, widely accepted term for a liquid that has contaminants is contaminated.
