The correct option is C Glucose 6p to Fructose 6p
Glycolysis or one of the alternative pathways, pyruvic acid can be further oxidized by a transitional step involving a process called Decarboxylation. In this step, an enzyme-containing coenzyme A removes a carbon dioxide molecule producing a new two-carbon intermediate called acetaldehyde from Glucose 6p to Fructose 6p. so, 'the correct option is Glucose 6p to Fructose 6p'.
