Craig is drawing a staircase from the point of view of looking downward from the top. this creates an image of stairs cascading in a downward spiral. there is a blue light coming from the bottom. what are the features of this drawing that make it have rhythm? the light source b the curve of the stair rail c the stairs d the high perspective

C) The stairs, because rhythm is repeated elements in photography, like books/kayaks/chairs in a row.

A) would be emphasis, not rhythm, because there's no repetition of the blue light (it's emphasis because the spiral staircase leads to the blue light).
B) would be line, not rhythm, because there are no repeated elements.
D) would be perspective, not rhythm, because being high up doesn't have anything to do with rhythm.
