Is It Possible to Determine Whether a Diagram Represents an Argument

Is it possible to determine whether a diagram represents an argument or an explanation if there is no information beyond the diagram itself?

B) No, because all parts of the diagrams are analogous.
C) Yes, because explanations never have dependent hypotheses.
