Explanation:
The correct answer is segmentation. <span>The annelids also known as segmented worms, are bilaterally symmetrical invertebrate organisms. Their main characteristic is a segmented body. Annelid's body consists of segments that are identical (except the first and the last one), having the same sets of internal organs and external chaetae.

Answer:
The correct answer is A. stabilizing selection
Explanation:
Stabilizing selection is one type of natural selection that occurs when the population having non-extreme traits are stabilized. It results in overexpression of a particular trait in a population. Here most average individual gets selected.
So as the stabilizing selection favors the middle phenotype and not extreme phenotypes it decrease the genetic variation. So here individuals who are having extremely long snout are selected therefore a particular trait is selected and overexpressed in the population. So it is an example of stabilizing selection.
