Vine charcoal is a long and thin piece of charcoal that came from burning sticks or vines, it is ideal to be used in basic compositions of drawing. Compressed charcoals are a block form of a stick that has a greater intensity and is harder than vine charcoal. While powdered charcoal is used for creating patterns and transferring techniques in art.
I believe it would be <em>A. pastiche</em>
It wouldn't be B or C, as both is an art..genre? itself, and definitely not D, as it would still be their original artwork in a way.
Hope this helps! :)
