What is a cordon?

A cordon refers to a type of barrier that is often used to control access to a specific area. Typically made from materials such as cord, ribbon, or tape, it serves the purpose of marking boundaries and ensuring that only authorized individuals can enter restricted zones. This can be seen in various settings, such as in crowd control at events, construction sites, or emergency situations where safety and security are paramount. The visual aspect of a cordon helps in guiding people and offering clear indications of where they should or should not go, making it an effective tool for maintaining order and safety in public and private spaces.

The other options present concepts that do not align with the definition of a cordon, which is specifically about creating a physical barrier rather than emotional states, spending habits, or fashion choices.
