By Currently Included, $D \isin L$.

So $D \isin R^+$.
\subsection{Unique Base}
-Into Base means that $C \in \pqn$, so Unique Base is not
+Into Base means that $C \in \pln$, so Unique Base is not

-By Into Base and Base Acyclic for $L$, $D \isin L \implies D \not\in \pqy$.
-And by Into Base $C \not\in \pqy$.
+By Into Base and Base Acyclic for $L$, $D \isin L \implies D \not\in \ply$.

Now from Desired Contents, above, $D \isin C

-$\implies D \not\in \pqy$. $\qed$.
+$\implies D \not\in \ply$. $\qed$.
