Which among the following is a natural biopolymer of monosaccharides?

$C_{1}-C_{4}$ glycosidic bond is not found in

Observe the following statements.
$I$. Sucrose has glycosidic linkage.
$II$. Cellulose is present in both plants and animals.
$III$. Lactose contains $D$-galactose and $D$-glucose units.
Which of the following statements are correct?

$L$-isomer of a compound $A$ $(C_{4}H_{8}O_{4})$ gives a positive test with $[Ag(NH_{3})_{2}]^{+}$. Treatment of $A$ with acetic anhydride yields a triacetate derivative. Compound $A$ produces an optically active compound $B$ and an optically inactive compound $C$ on treatment with bromine water and $HNO_{3}$ respectively. Compound $A$ is ....

Match List-$I$ with List-$II$:

List-$I$	List-$II$
$A$. Glucose $+ HI$	$I$. Gluconic acid
$B$. Glucose $+ Br_{2}$ water	$II$. Glucose pentacetate
$C$. Glucose $+$ acetic anhydride	$III$. Saccharic acid
$D$. Glucose $+ HNO_{3}$	$IV$. Hexane
