(B) what is called aperiodic tiles, describes
(C) aperiodic tiles, describing
(D) so-called aperiodic tiles, describe
(E) aperiodic tiles, it turned out to describe

Why not B?

Probably because tile"s" is plural....

IMO if we do not know whether the thing is singular or plural...then better to go with the case given in the question itself....

Well, the choices are between A and B.

In B, "what is called X tiles" is wrong. "The work...describes" is correct.

A is correct in terms of grammar and also preserves the meaning.
