Physical systems like roads, ports, and railways that support movement are known as

• A. Infrastructure
• B. Justify
• C. Interdependence
• D. Multilateralism

Answer: (A)

Infrastructure is the term for the physical systems that enable movement, such as roads, ports, and railways. These networks are foundational assets that connect places, support trade, and enable people and goods to move efficiently. They’re long‑lasting investments that governments and private groups build and maintain to keep the economy functioning. The other options don’t fit because “justify” is a verb meaning to prove something, not a system; “interdependence” refers to mutual reliance among parts or actors; and “multilateralism” describes cooperation among many parties, usually countries, rather than physical networks.
