Correct Answer:
C. Pollute
Antonyms are words that have opposite meanings. The word “distil” refers to the process of purifying a liquid by heating and cooling, separating its components to make it cleaner or more concentrated.
- “Pollute” is the correct antonym. To pollute means to contaminate something, making it impure or dirty, which is the direct opposite of purifying.
- “Extract” is incorrect; it means to remove or obtain something, often a component, which can be part of the distillation process.
- “Purify” is incorrect; it is a synonym of distil, meaning to make something clean or pure.
- “Refine” is incorrect; it means to remove impurities or undesirable elements, also similar to distil.
