Identify the correct statements.
$A$. Glucose exists in two anomeric forms.
$B$. Anomers of glucose differ in configuration at $C-1$ in cyclic hemiacetal structure.
$C$. Melting point of $\alpha$-anomer of glucose is greater than $\beta$-anomer.
$D$. Specific rotation of $\alpha$-anomer is $+19^\circ$ while for $\beta$-anomer is $+112^\circ$.
$E$. $\alpha$ and $\beta$-anomers of glucose are prepared by crystallization of saturated glucose solution at $303 \text{ K}$ and $371 \text{ K}$ respectively.

Select the incorrect pair.

Glucose molecule reacts with $X$ number of molecules of phenylhydrazine to yield osazone. The value of $X$ is

$\alpha-D$-glucose and $\beta-D$-glucose differ from each other due to the difference in the configuration of one of the carbons.
