help, please the answer is wrong.

A Fischer projection of a monosaccharide is shown below: a. Classify this monosaccharide (e.g., aldotriose) b. Does it have the D or L configuration? c. Which carbon and oxygen become bonded in the furanose ring form of this monosaccharide (e.g., C2O6, where O6 means the oxygen on carbon 6 , or "not formed")? d. Which carbon and oxygen become bonded in the pyranose ring form of this monosaccharide e.g., C2O6 or "not formed"? 2 more group attempts remaining
