A and B are correct. Representational art relies on a real item from reality. As does abstract, but it is twisted somewhat. Non-representational isn't from an object - it's purely aesthetic, aka psychedelic shapes and patterns.
Renaissance art completely revitalized the entire concept of art in Europe. It branched out beyond the merely religious purpose of medieval artwork. It reflected a new humanist philosophy, and it engaged with its viewer in a novel yet natural way that had not been done since the end of the classical period.
