On prolonged heating with $HI$,glucose gives a compound '$C$',which can be obtained by Wurtz reaction using sodium metal and compound '$D$'. Identify '$D$'.

The carbohydrate present in $DNA$ is $2$-deoxy-$D$-ribose. Which of the following statements are correct regarding this sugar?
$A.$ It is a pentose sugar.
$B.$ It is present in pyranose form.
$C.$ It is in $D$-configuration.
$D.$ It is a reducing sugar when free.
$E.$ It is in $\alpha$-anomeric form.
Choose the correct answer from the options given below:

Given below are two statements.
Statement $I$: Maltose has two $\alpha$-$D$-glucose units linked at $C_1$ and $C_4$ and is a reducing sugar.
Statement $II$: Maltose has two monosaccharides: $\alpha$-$D$-glucose and $\beta$-$D$-glucose linked at $C_1$ and $C_6$ and it is a non-reducing sugar.
In the light of the above statements,choose the correct answer from the options given below.

Match List-$I$ with List-$II$.

List-$I$ (Biopolymer)	List-$II$ (Monomer)
$A$. Starch	$I$. nucleotide
$B$. Cellulose	$II$. $\alpha$-glucose
$C$. Nucleic acid	$III$. $\beta$-glucose
$D$. Protein	$IV$. $\alpha$-amino acid

Choose the correct answer from the options given below:

Given below are two statements :
Statement $I :$ $D$-glucose pentaacetate does not react with $2,4$-dinitrophenylhydrazine.
Statement $II :$ Starch,on heating with dilute sulfuric acid at $393 \ K$ and $2-3 \ \text{atmosphere}$ pressure,produces glucose.
In the light of the above statements,choose the correct answer from the options given below.
