Query: Commutative C*-subalgebras of simple stably finite C*-algebras with real
  rank zero   Let X be a path connected, compact metric space and let A be a unital
separable simple nuclear Z-stable real rank zero C*-algebra. We classify all
the unital *-embeddings (up to approximate unitary equivalence) of C(X) into A.
Specifically, we provide an existence and a uniqueness theorem for unital
*-embeddings from C(X) into A.
