Glucose reacts with acetic anhydride to form

$D-(+)$-glucose reacts with hydroxylamine and yields an oxime. The structure of the oxime would be:

Which of the following statements support the cyclic form for glucose?
$(i)$ It does not give Schiff's test.
$(ii)$ It is found to exist in two different crystalline forms.
$(iii)$ It oxidises with nitric acid to give saccharic acid.
$(iv)$ Pentaacetate of glucose does not react with hydroxylamine.

The letter '$D$' in $D$-glucose signifies
