Answer - D - The flying buttress is the Gothic-era stone arch and its pier that work together to support a roof from a pillar outside the building.

Key Takeaway: The flying buttress is the most notable innovation of the Gothic period. First appearing on Notre Dame de Paris, these stone arches work to support the roof by transmitting the force of the vaulted ceiling down through the walls to a counterweight outside of the building. This enabled buildings to be taller and have more window space, especially for stained glass. Additionally, the buttresses helped to stabilize the building and prevent wind damage from hurting the cathedrals, which were usually very tall and very narrow.
