Which of the following is considered infrastructure?

Infrastructure typically includes the foundational systems and structures that support the functioning of a community or economy. This encompasses public facilities and services essential for transportation, sanitation, and overall public welfare.

Choosing roads and sewer systems is accurate because these elements are fundamental aspects of public infrastructure. Roads facilitate transportation and connectivity, while sewer systems ensure proper waste management and sanitation, both critical for public health and urban development.

While vehicles and equipment, buildings for public housing, and office furniture may support government operations or provide services to the public, they do not fall under the standardized definition of infrastructure in the same way that roads and sewer systems do. Vehicles and equipment might be operational tools, and buildings for public housing serve residential purposes, whereas office furniture is simply a part of office amenities. None of these categories carry the broad, foundational significance attributed to infrastructure in community planning and economic development.
