Despite the similarities, methylene chloride (or dichloromethane) is superior to ethylene chloride as an extraction solvent because the boiling point of methylene chloride is lower than the boiling point of ethylene chloride, which allows it to be removed more easily.

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.
