• C. 8
• D. 9

Answer: (D)

Dangerous goods are classified into a maximum of nine classes based on their hazards or risks associated with transportation. Each class addresses a specific type of danger, helping to ensure appropriate handling, transport, and emergency measures are taken.

The classes include various categories such as explosive materials, flammable liquids, toxic substances, and radioactive materials, among others. By having these distinct classifications, regulations can be effectively enforced to maintain safety standards across the transport sector. This classification system is crucial for shipping and handling dangerous goods, as it helps responders understand the types of risks they may encounter.

While some materials may fall into multiple categories depending on their properties, the overarching structure allows for safe management and regulatory compliance across the industry.
