Which are come of the advantages of body segmentation?
a. the body plan can be easily repeated
b. segments can become specialized on a particular function
c. the animal can develop bilateral symmetry
d. it allows the evolution of a central nervous system.

b. Segments can become specialized on a particular function

Explanation:

Segmentation conditions virtually every aspect of the structure and functioning of animals with a consecutive body. Generally speaking, we can say that the main advantage of segmentation is that each segment can become specialized in a specific function.

One of its advantages is related to locomotion and comes, on the one hand, from the fact that the volume of celiac fluid remains constant in each compartment, acting as an antagonistic force against which muscles can act and, on the other, from the possibility of independently control each segment . This allows the peristaltic movement (circular muscle contraction wave followed by longitudinal muscle contraction) to be localized and involve only those muscles that are strictly necessary, making the movement's energy needs considerably more profitable.

The compartmentalization of the body led to the repetition of structures, namely excretory, nervous and circulatory in each segment. This can be seen as another advantage of segmentation as it may lessen the impact of damage to the animal's body; Undamaged segments can maintain their normal functions and thus increase the likelihood that the animal will overcome the damage sustained.

Another advantage is that segmentation allows modification of certain portions of the body to perform specialized functions such as feeding, locomotion and reproduction.
