The answer is Atom.
Explanation:
The atom is the smallest constituent unit of matter that has the properties of a chemical element and that it is not possible to divide by chemical processes. The atom is formed by a nucleus with protons and neutrons and several orbital electrons (subatomic particles); whose number varies according to the chemical element. Atoms combine to form molecules that then interact to form solids, liquids and gases.

Answer:
C. The common ancestors of these owls were geographically isolated, and over time the allele frequencies changed so much they are no longer able to interbreed.
Explanation:
This is an example of allopatric speciation. Allopatric speciation, also called geographical speciation, involves the development of a new species when the ancestral population becomes separated by geographical barriers such as a river or a mountain range. This could also take place when the ancestors of the two species emigrate to another area.
In different geographic locations, the separated ancestors undergo gradual evolutionary changes, ultimately, the the two species become so genetically diverse that they cannot interbreed.
