The answer is B. For sure
In his painitng Christ Entering Jerusalem, <span>the artist Duccio pioneered the use of architecture to define space and direct movement.
In art, Define space is a technique to left some part of the canvas unoccupied and direct movement is a technique that try to capture a moving subject/object into artform, and both of these techniques could be seen on the painting.</span>
I agree
just because art is in a different form does not mean that its not art
in a matter a fact it is more of art because its different.
