Final answer:
The competition entry by Lorenzo Ghiberti for the bronze doors of the baptistery in Florence depicted the sacrifice of Isaac; the later work known as 'The Gates of Paradise' depicted scenes from the Old Testament. Option C is correct.
Step-by-step explanation:
The Renaissance began with a significant competition in 1401 for the commission to create bronze doors for the baptistery of Florence, marking the start of Renaissance sculpture. The subject of the entry panels for this competition, which was won by Lorenzo Ghiberti, was the sacrifice of Isaac.
However, the option closest to the content in the question is C. The Gates of Paradise, which refers to the later work by Ghiberti that decorated the eastern entrance of the Florence baptistery, consisting of panels depicting scenes from the Old Testament. The choice B. The Creation of Adam does not appear in the competing panels from 1401 but is rather a subject depicted on the ceiling of the Sistine Chapel by Michelangelo in the 16th century.
Therefore, the correct answer for the subject of the entry panels in the 1401 competition won by Ghiberti is not explicitly listed among the choices provided, but the answer relevant to the subsequent work by Ghiberti on the baptistery is 'The Gates of Paradise'.
