Which of the following items is NOT allowed in cabin baggage?

The item that is not permitted in cabin baggage is safety matches. This restriction is in place because safety matches are considered a fire hazard. Aviation regulations prioritize safety in the cabin, and items that can potentially ignite or cause fire are heavily restricted.

In contrast, clothing, cosmetics, and sporting goods are generally acceptable items in cabin baggage as long as they comply with size and weight regulations. Clothing is a basic necessity for travelers, cosmetics typically include personal hygiene products, and sporting goods are permitted as long as they do not include items that are sharp or pose a threat to the safety of other passengers. Each of these categories follows specific guidelines that ensure they can be safely accommodated in the cabin without compromising passenger safety.
