All hair color products are organic chemicals. What does this imply about their composition?

• A. They contain carbon and hydrogen
• B. They contain carbon and oxygen
• C. They contain hydrogen and nitrogen
• D. They contain carbon, hydrogen, and nitrogen

Answer: (A)

Organic chemicals are built around carbon atoms bonded to hydrogen, forming a carbon–hydrogen framework. If all hair color products are organic, their basic composition must include carbon and hydrogen. That’s why carbon and hydrogen is the correct implication. Some organic ingredients may also contain oxygen or nitrogen, but those elements aren’t required for something to be considered organic in this context, and not all hair color components have them. The presence of carbon and hydrogen is the defining takeaway here, whereas requiring other elements would unnecessarily exclude many hair color ingredients.
