The answer is B. Private sector
The federal government plays a significant role in regulating and overseeing critical infrastructure, but it is not primarily responsible for the operation and maintenance of utilities and banking. Instead, it provides guidelines, regulations, and support to ensure these sectors are secure and resilient.
The private sector is primarily responsible for the operation and maintenance of critical infrastructure such as utilities and banking. Most utilities (like electricity, water, and telecommunications) and banking institutions are privately owned and operated. The private sector is tasked with ensuring the reliability and security of these services, often in collaboration with government agencies.
State governments have regulatory and oversight roles, particularly in areas like public utilities commissions. However, they are not the primary operators of utilities and banking services, which are largely managed by private entities.
Local governments may have some involvement in utilities, especially in terms of local water and waste management services, but they are not primarily responsible for the broader categories of utilities and banking, which are largely managed by the private sector.
