The medium of an artistic work is C. The way something is communicated, or the material something is created from
.
Explanation:
The term <em>medium </em>in arts has two overlapping meanings: it can refer to either the type of art or the way something is communicated-painting, drawing, sculpture-, or to the material the artistic work is made from -bronze, marble, canvas, watercolour, pencil, crayon, etc.
A medium refers to the materials that are used to create a work of art. None of your answers are exactly right but I would go with C. Since the medium could be the background that something is created from.
