Look at this painting by Duccio. This painting departs from earlier medieval art because it:

B. depicts Christ's life on earth.

Explanation:

In early medieval art and the periods that came before, the figure of Jesus Christ was only shown as the figure in heaven. His life on earth amongst humans was not present in the art pieces. Duccio, the Italian painter, is one of the first artists who started painting Jesus Christ’s life on the earth.

The painting in question is Appearance While the Apostles are at Table. Jesus Christ is showing presenting himself to his disciples, apostles who sit at the table and listen to him speaking God’s words.

The images presented in this phase of medieval art were still limited to a certain array of subjects, such as presentations of the last supper, the raising of Lazarus, entry into Jerusalem, Christ with apostles, etc. These stories of Christ’s life on earth were taken from the bible and show the influence of his religious and spiritual ways on people.
