The central idea of Raphael's "School of Athens" painting is:
A. The philosophy is the queen of the sciences.
In this painting, Raphael portrays various philosophers from ancient Greece, such as Plato and Aristotle, engaged in discussion and debate. The figure representing Plato is pointing upwards, symbolizing his belief in the world of ideas and philosophy as the highest form of knowledge. On the other hand, Aristotle's hand is stretched out horizontally, representing his emphasis on empirical observation and the natural world. This contrast reflects the central idea that philosophy, with its pursuit of wisdom and truth, is the pinnacle of all disciplines.
