The correct answer is A. The painter who is usually considered the first naturalistic artist was Masaccio.
Explanation:
Masaccio was an Italian painter. He was one of the initiators of the Renaissance in Florence, renewing the painting according to a new rigorous vision, which rejected the decorative excesses and the artificiality of the then dominant style, the international Gothic. He inserted very vivid figures and with good readiness to the similitude of the true, in credible architectures and landscapes, modeling them through the use of chiaroscuro.
