Infrastructure also refers to ...

• A. the underlying features; framework
• B. a country's basic systems, such as power, water or transportation
• C. the scenic beauty of a city
• D. the legal framework

Answer: (B)

Infrastructure refers to the basic systems and facilities that a country or region needs to function, supporting everyday life and economic activity. This includes tangible networks like power, water supply, and transportation. That’s why describing infrastructure as a country’s basic systems such as power, water, or transportation is the most accurate fit.

Other options miss this core idea: scenic beauty relates to aesthetics rather than essential services; the legal framework covers rules and laws rather than physical systems; and “underlying features; framework” is too vague and general to capture the practical networks that infrastructure encompasses.
