Statement I: Glucose and fructose both reduce Schiff's reagent.
Statement II: Both have free carbonyl group.

Options

A. Statement `I` is true, Statement `II` is true, Statements `II` is the correct explanation of Statement `I`.
B. Statement `I` is true, Statement `II` is true, Statement `II` is not the correct explanation of Statement `I`.

D. Statement `I` is false, Statement `II` is true.
