The answer is C.
Transgenic means that one or more DNA sequences from another species has been introduced by artificial means. For example, animals usually are made transgenic by having a small sequence of DNA injected into a fertilized egg or developing  embryo. Transgenic plants can be made by introducing foreign DNA into a variety of different tissues.
Most transgenic organisms are generated in the laboratory for research purposes. Others have been developed for commercial purposes  such as golden rice that has been modified to produce beta-carotene, the precursor to vitamin A. 
 
        
                    
             
        
        
        
Answer:
anwser is C
Explanation:
they both have 6 carbon atoms so A is wrong
both are monosacchride so B is wrong
both have same molecular formula which is (C₆H₁₂O₆) so D is wrong
in glucose the anomeric carbon is the first carbon, whereas in fructose, the anomeric carbon is the second carbon. The anomeric carbon is the one containing the carbonyl group (carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom: C=O)
