Answer: (B)

Critical infrastructures encompass the systems and assets that are vital for the functioning of society as a whole. These infrastructures are essential for maintaining public health and safety, economic stability, and national security. They include a wide range of sectors such as transportation, energy, water supply, communications, and healthcare, among others. When these infrastructures are compromised, it can lead to significant disruptions that affect the daily lives of citizens and the overall stability of the nation.

The importance of critical infrastructure is underscored by the need for resilience and security measures to protect these systems from physical and cyber threats, ensuring that essential services are maintained even in times of crisis. Understanding the broad definition and significance of critical infrastructure is crucial for professionals in IT security, as they play a key role in safeguarding these assets from potential vulnerabilities.

While other choices mention important aspects of national defense and policies, they do not encompass the broader concept of critical infrastructures that are fundamental to the functioning of society at large.
