Which of the following carbohydrates produces double the quantity of glucose on hydrolysis per mole as compared with sucrose?

Given below are two statements:
Statement $I$: The two cyclic forms of $D-(+)-glucose$ ($\alpha$ and $\beta$ anomers differing at $C1$ hydroxyl orientation) are two anomers of $D-(+)-glucose$.
Statement $II$: The open chain forms of $D-glucose$ and $D-fructose$ contain three similar chiral carbons at $C3$,$C4$,and $C5$.
In the light of the above statements,choose the correct answer from the options given below:

What is the maximum value of $x$ in the following reaction?
$MeO-CH-(CHOH)_3-CH-CH_2OH$ (with a cyclic ether linkage between the first and fifth carbon) $+ xHIO_4 \rightarrow$ products

Which is a reducing sugar?

Assertion : Glycosides are hydrolyzed in acidic conditions.
Reason : Glycosides are acetals.

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.
