• B. Food items, cosmetics, books, clothing.
• C. Electrical devices, jewelry, water.
• D. Medicines, batteries, electronics.

Answer: (A)

Dangerous goods are items that can pose safety risks on an aircraft, especially in the confined cabin. They must not be carried unless the airline and authorities explicitly permit them and the items are properly packaged and labeled. Flammable liquids, oxidizers, compressed gases, and corrosives fall into this group because each of these has the potential to start or intensify a fire, cause an explosion, or damage the aircraft and passengers if released or misused. That risk is why they require special handling and authorization for transport in the cabin. The other items listed—food, cosmetics, books, clothing—are not considered dangerous goods under normal cabin rules and are generally allowed. Electrical devices, jewelry, water likewise aren’t designated as dangerous goods in the broad sense (though some batteries or devices have separate, specific restrictions). Medicines, batteries, and electronics may have their own rules, but as a general category they do not belong in the dangerous-goods group that is prohibited in the cabin without special permission.
