A _____ is an urban area consisting of at least two metropolises and their many suburbs.

• A. Conurbation
• B. Megacity
• C. Megalopolis
• D. Metropolitan area

Answer: (C)

When several adjacent metropolitan areas grow until they merge into a long, continuous urban region, that larger zone is called a megalopolis. It specifically refers to an urban area made up of at least two metropolises and their many suburbs, connected to form one expansive belt. A megacity is about a single city exceeding a population threshold, not about linking multiple cities. A metropolitan area centers on one core city and its surrounding suburbs, usually within one integrated system. A conurbation is a broad term for a large urban area created by merging cities, which can resemble a megalopolis but the defining idea here is the extensive chain of multiple cities across a wide region, captured by the term megalopolis.
