Officials working for the National Biking Association have made different claims about how Jordan Jones won the American Cycling Classic this year. Right now, which claim do you think is the strongest?

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

i believe the answer would be b. hope it : )
