Is the Plato crater a basin or ringed crater or is it a flooded crater?

Answer:
Plato is a "flooded" crater that filled with lava after it was created by an impact. A large one. It's floor is relatively flat and largely unscarred (save for a few small craters). A link can be found below for more information.
