Which of the following best identifies the artistic achievement of Giotto di Bondone

The artistic achievement of Giotto di Bondone is best identified as the pioneering precursor to the Renaissance art movement in the 14th century. Giotto's innovative use of naturalistic and three-dimensional figures, as well as his ability to convey emotion and depth, marked a shift away from the flat and stylized Byzantine art of the time. His frescoes in the Scrovegni Chapel in Padua are particularly notable for their groundbreaking approach to depicting human subjects and narrative.
