Alizarin, a dye derived from the madder root, is an example of which type of dye based on source?
Correct answer: C. Natural dye
- A. Synthetic dye
- B. Animal dye
- C. Natural dye
- D. Mineral dye
Explanation
The correct answer is Natural dye. Alizarin is extracted from the madder root, which is a plant-based source, fitting the definition of a natural dye. Synthetic dyes are chemically manufactured, animal dyes are derived from animals, and mineral dyes are sourced from minerals or inorganic materials. Since Alizarin's source is botanical, it falls under the category of natural dyes.
