The correct answer is C. Chiaroscuro
If you look at both Zurbaran and Caravaggio’s works, you’ll notice a very
dramatic manipulation of light and shading. This use of intense shading is
called chiaroscuro.
Chiaroscuro is actually a combination of two Italian words meaning Chiaro =
Light and Oscuro = Dark, and this also refers to the shades of lighting in the
painting.
