Michelangelo' s sixteenth-century Sistine Chapel paintings are currently being restored. A goal of the restorers is to uncover Michelangelo' s original work, and so additions made to Michelangelo' s paintings by later artists are being removed. However, the restorers have decided to make one exception: to leave intact additions that were painted by da Volterra. Which one of the following, if true, most helps to reconcile the restorers'decision with the goal stated in the passage?
A: Michelangelo is famous primarily for his sculptures and only secondarily for his paintings, whereas da Volterra is known exclusively for his paintings.
B: Da Volterra's work is considered by certain art historians to be just as valuable as the work of some of the other artists who painted additions to Michelangelo's work.
C: The restorers believe that da Volterra stripped away all previous layers of paint before he painted his own additions to the Sistine Chapel.
D: Because da Volterra used a type of pigment that is especially sensitive to light, the additions to the Sistine Chapel that da Volterra painted have relatively muted colors.
