Monosaccharides Memes

The organic chemistry nightmare we've all feared! The question asks for the name of C₆H₁₂O₆, but the evil twist is that ALL five answers are correct. These are all monosaccharide isomers with identical molecular formulas but different structures. The real chemistry student panic sets in when you realize glucose, allose, mannose, fructose, and galactose are just different arrangements of the same atoms. It's like asking "which identical quintuplet is named Bob?" when they're all named Bob, just standing in different poses.
