Individual pyrrole molecules readily join together into larger molecules called polypyrroles. If polypyrroles form from pyrrole

in the presence of zeolites, they do so by attaching to the zeolite either in lumps on the outer surface of the zeolite or in delicate chains within the zeolite's inner channels. When zeolite changes color from yellow to black, it means that on or in that zeolite polypyrroles have formed from pyrrole. Yellow zeolite free of any pyrrole was submerged in dissolved pyrrole. The zeolite, turned black even though no polypyrroles formed on its outer surface.
If the statements above are true, which one of the following must on the basis of them be true?
(A) Polypyrroles had already formed on or in the zeolite before it was submerged.
(B) Lumps of polypyrrole attached to the zeolite were responsible for its color change.
(C) At least some of the pyrrole in which the zeolite was submerged formed polypyrrole chains.
(D) None of the pyrrole in which the zeolite was submerged attached itself to the zeolite.
(E) Little, if any, of the pyrrole in which the zeolite was submerged reached the zeolite's inner channels.
