Which term refers to an electrical supply distribution network that can be national or international, allowing electricity to move across borders?

• A. Global Grid Network
• B. National and International Grid Systems
• C. Transnational Power Grid
• D. International Electricity Network

Answer: (B)

Interconnected power grids that span borders allow electricity to move from one country to another, balancing supply and demand across regions. The term that best captures a distribution network capable of operating at both national and international levels is National and International Grid Systems. It clearly signals that each country maintains its own grid while also linking with others to form wider interconnections for cross-border power flow. The other options imply broader or less precise ideas—one suggests a single global system that doesn’t really exist; another uses a term that’s less commonly used in this context; and another describes an international network without emphasizing the dual national level. So this phrase is the most accurate way to describe a distribution network that can operate nationally and across borders.
