Which area is NOT part of the security zone?

The assessment zone is the correct answer because it does not fall under the defined categories associated with security zones. Security zones are specifically designed areas that have set protocols for controlling access and ensuring safety in specific maritime contexts.

The patrol zone, control zone, and safety zone are all integral components of security operations. The patrol zone is typically designated for law enforcement or security personnel to monitor and assess maritime activities. The control zone is where access is restricted and monitored closely to deter unauthorized entry. The safety zone is intended to protect persons and property from hazards, ensuring that secure operations can continue safely.

In contrast, the assessment zone is more associated with intelligence gathering and evaluation rather than a defined physical space where security protocols are actively enforced. Thus, the assessment zone does not fit the specific criteria for a security zone, making it the correct choice in this context.
