The correct option is D Dihydroxyacetone phosphate and 3-phosphoglyceraldehyde
During glycolysis, fructose 1, 6-bisphosphate is split into 2-3 carbon compounds, i.e. Dihydroxyacetone Phosphate (DHAP) and 3-phosphoglyceraldehyde (3-PGA).
Both these substrates are interconvertible to each other by triose phosphate isomerase enzyme.
