Suggested answer: B

Explanation:

A data diode is known as a prebuilt directional gateway that is unidirectional, designed specifically to allow data to travel in only one direction, ensuring secure one-way communication. This feature makes data diodes ideal for environments where it is critical to prevent any possibility of data leakage or unauthorized access from an external network back to a secure network. Data diodes are commonly used in military and industrial applications, including ICS/SCADA systems, to protect sensitive information.
