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.

$CHO-(CHOH)_4-CH_2OH \xrightarrow{HIO_4} \text{Product}$. Identify the product.

Glucose reacts with phenylhydrazine to form osazone. How many moles of phenylhydrazine are consumed in this reaction?
