Solution
The correct option is A Bilateral
Correct answer is B.Animals with bilateral symmetry have anterior end differentiated into head. Also the concentration of the nervous system is higher at anterior end, which efficiently coordinate with the sense organs, which allows a more coordinated bodily functions in response to a stimuli. This characteristic is absent in radial or spherical symmetrical organisms. Therefore, bilateral symmetrical organisms exhibit faster response to any external stimuli.
