(A) The sugar present in $DNA$ is $\beta-2$-deoxy-$D$-ribose.$1$. It is a pentose sugar because it contains $5$ carbon atoms ($A$ is correct).$2$. It exists in furanose form (a $5$-membered ring),not pyranose form ($B$ is incorrect).$3$. It has the $D$-configuration ($C$ is correct).$4$. It is a reducing sugar because it has a hemiacetal group at the $C1$ position,which can open to form an aldehyde ($D$ is correct).$5$. In $DNA$,it exists in the $\beta$-anomeric form,not the $\alpha$-anomeric form ($E$ is incorrect).Therefore,statements $A, C,$ and $D$ are correct.
