I believe it's A because as the Greeks advanced in time their overall structural design became more elaborate.
Over time, much of the influence of the Mongols has become more of a background to other historical developments. Important trades shifted away from the Silk Road, and the New World gained a greater significance in the global economy. However, one area that the Mongol invasions have continued to affect is in demographics. Central Asia has experienced some of the greatest changes, where the decline of Indo-Aryan or Indo-European languages, such as those based for Persian, reflect a shift more to Turkic type languages. This also likely reflects greater presence of Turkic populations as they increasingly moved across Central Asia during the period of conquests that saw major cities and populations removed. Such migrations had begun in the 11th century but increased further. Many regions remained relatively depopulated for centuries, such as Iran and Iraq, where those regions had once supported far larger populations and those levels of populations did not fully recover until perhaps the 20th century. This also meant these regions became less significant in global affairs, as new powers arose to replace them in the Near East and surrounding regions.
invasions may have contributed to its isolationist policies that started in the late 15th century. The outside began to look like an uncivilized place, where the Mongol destruction was still relatively fresh on the mind of Chinese rulers, leading to a greater focus away from the rest of the world
