Which of the following is an example of a prohibited item?

Choosing an explosive device as an example of a prohibited item is correct because such items pose a significant threat to safety and security. Explosive devices are inherently dangerous and can cause extensive harm, injury, and loss of life, which is why they are strictly forbidden in secure environments like airports or secured facilities.

In contrast, items such as laptops, books, and soft drinks are generally permissible and do not present an immediate threat to safety or security under normal circumstances. While there may be specific restrictions on the use of certain electronics or beverages in security-sensitive areas, they do not carry the same level of risk as explosive devices do. Thus, the identification of an explosive device as a prohibited item highlights a clear understanding of the types of hazards that security protocols aim to mitigate.
