Which of the following is not a critical infrastructure component?

• A. Information and communications
• B. Public health services
• C. Transportation
• D. Food supply

Answer: (D)

The concept being tested is which sectors are designated as critical infrastructure components in risk-management and protection frameworks. These components are those whose continued operation is essential to national security, the economy, and public safety.

Information and communications is foundational because it enables coordination, data flow, and access to services across all other sectors. Public health services are critical for preventing, detecting, and responding to health threats, protecting the population. Transportation underpins the movement of people, energy, and goods, and it enables emergency response and economic activity.

Food supply, while absolutely vital to daily life, is typically categorized under a broader Food and Agriculture sector rather than treated as a standalone critical infrastructure component in many frameworks. In this context, it isn’t listed as a separate critical infrastructure component, which is why it is identified as the correct choice.
