The correct answer is A) human beauty.
Human beauty would MOST likely have been a topic of artists of the Italian Renaissance.
After many years of dark ages during Medieval times, at the end of the 14th century, beginning of the 15th, some Italian artists and thinkers suggested that a new period has to be born. A period where learning, art, and culture would change people's perspectives about humans, life, and nature: the Renaissance. At that time, there was no country of Italy but powerful city-states governed by wealthy families. That was the case of Florence, ruled by the rich Medici family that patronage the work of artists such as Michelangelo.
