Anne is observing an animal specimen. it has body parts that seem to extend from a central point, just like spokes in a bicycle wheel. which animal is it most likely to be?

sponge

flatworm

crayfish

The answer is sponges.

Animals with the radial symmetry of the body have body parts that seem to extend from a central point, just like spokes in a bicycle wheel. 

Through the process of elimination:
Sponges have radial symmetry.
Flatworms have bilateral symmetry.
Crayfish have bilateral symmetry.

Therefore, among all choices, only sponges have body parts that seem to extend from a central point, just like spokes in a bicycle wheel.
