Which of the following is a medieval monumental building?

• A. Medieval cathedrals
• B. Iron Triangle
• C. Gantt chart
• D. Kanban

Answer: (A)

Monumental buildings from the medieval period are large, enduring stone structures built to inspire awe and serve religious or civic life. A medieval cathedral fits this idea perfectly, with massive stone construction, flying buttresses, and tall spires that create a sense of grandeur and accommodate great crowds—designed to stand for generations and symbolize the era’s faith and power. The other terms refer to modern planning tools or diagrams rather than architectural works: an Iron Triangle is about balancing project constraints, a Gantt chart maps out a schedule, and Kanban is a workflow method. Since only the cathedral represents a true medieval monumental building, it is the best choice.
