Which reagent forms a crystalline osazone derivative upon reaction with glucose?

Which of the following is a reducing sugar?

Among the three compounds shown below,two yield the same product on reaction with warm $HNO_3$. The exception is:

Glucose and Fructose are .......

Which one of the following structures represents amylose?

Given below are two statements:
Statement $I$: Sucrose is dextrorotatory. However,sucrose upon hydrolysis gives a solution having a mixture of products. This solution shows laevorotation.
Statement $II$: Hydrolysis of sucrose gives glucose and fructose. Since the laevorotation of glucose is more than the dextrorotation of fructose,the resulting solution becomes laevorotatory.
In the light of the above statements,choose the correct answer from the options given below.
