Answer:
C.The two species do not breed in the same area, so they are reproductively isolated by allopatry.
Explanation:
Allopatry means that these two species are geographically separated during the breeding season, so they are reproductively isolated.
Allopatric speciation is a form of speciation (creation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations  reach a high level  of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
