During the curdling of milk,what happens to the sugar present in it?

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:

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

List-$I$ $(\text{Saccharides})$	List-$II$ $(\text{Glycosidic linkages found})$
$(A)$ Sucrose	$(I)$ $\alpha 1-4$
$(B)$ Maltose	$(II)$ $\alpha 1-4$ and $\alpha 1-6$
$(C)$ Lactose	$(III)$ $\alpha 1-\beta 2$
$(D)$ Amylopectin	$(IV)$ $\beta 1-4$

Choose the correct answer from the options given below:

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