The correct answer is the catholic church.
After Rome's fall, the people of Europe turned to catholic church for stability and guidance.
It is during this fall that catholic churches continued to grow because,
1. Christianity was being proclaimed for the religion of masses.
2. The churches were organized socially, economically, and politically.
Roman empire split and Theodosius were the events which made christianity grew rapidly. Some of the reasons for the fall of Rome included,
1. Invasion by Barbarian tribes.
2. Overreliance on slave labour and economic troubles.
3. The rise of eastern empire.

B. its flying buttresses. Builders employed the first true flying buttresses (during the 1180s) to increase the window size and secure the soaring 115-foot-high vault. The <u>flying buttress</u>, an arched, skeletal exterior support, counters the lateral thrust of the nave vault and transfers its weight outward, over the side aisles (where it is resolved into and supported by a vertical external buttress, rising from the ground).
<em>The Notre Dame Cathedral (France) is the official seat of the Archbishop of Paris. Its architecture is one of the first examples of the use of flying buttresses, and the cathedral features numerous statues and </em><u><em>stained glass windows</em></u><em>. The original flying buttresses represented a structural innovation that would become central to the future development of Gothic architecture.</em>
