Which option correctly pairs the class with its hazard?

• A. Class 5 – Non-flammable gas
• B. Class 9 – Corrosive
• C. Class 7 – Radioactive
• D. Class 6 – Explosive

Answer: (C)

Hazard class identifies the general type of danger a material presents, and radioactive materials are designated as Class 7. That’s why pairing Class 7 with radioactive fits the standard classification, since Class 7 covers all materials that emit ionizing radiation and require special handling and protections. The other pairings mix up the classifications: oxidizers and organic peroxides are Class 5, not a non-flammable gas; corrosive substances are Class 8, not 9; and explosives fall under Class 1, not 6. So the pairing with radioactive correctly matches the official system.
