I believe the correct response would be B. Since of evolution were to occur, the possibility of the geographically isolated snakes to reproduce would be 0. Since the gene pool or the collection of all the genes in the population were to change and as a result of future reproductions of the 2 populations over time, transmission of specific genes that code for traits were to be specific for that population, ultimately not allowing them to reproduce.

For example, the food. When the dog smells food, it salivates. This is unconditioned because without teaching the dog, it automatically responds by salivating.
