Show answer and explanation

Correct answer: (A) Sears Tower, Chicago

Explanation

Sears/Willis Tower uses multiple connected structural tubes that terminate at different heights, the canonical bundled-tube example, A. The other buildings are associated with different structural systems. A tall building’s visual massing alone does not establish bundled-tube action.
