Which of the following is not one of the three greek orders?
a.
doric
c.
ionic
b.
classical
d.
corinthian

The correct answer is b. Classical. Greek orders are the architectural styles of Greek buildings, which are most easily depicted by looking at the tops of columns. In the Doric order, the top is simple and completely undecorated. The Ionic order is distinguished due to its scroll-like decorations at the top of columns. The Corinthian order is the most elaborate of the three. The top looks like a large basket with lots of leaves coming out of it. While "Classical" is not a Greek order, it is a larger subset that encompasses the Doric, Ionic, and Corinthian orders.
