Biology is the field of natural science that deals with study of life of organisms including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution.
The three branches branches of biology according to specification and type of organism are eukarya, bacteria and archaea.

The answer is D. Gene flow.
Gene flow is explained as the exchange of alleles from one population or another. In the statement, it was said that two wolf packs live in neighboring forests. This kind of setup may have lead for each wolf pack to develop traits or alleles which are exclusive to them. Now, come breeding season, they move to each other's area to breed. This process allows the alleles of each generation be exchanged with one another, creating a flow of genes from one population to another. The key concept to remember here is that: the species live in different areas and they interbreed to let alleles be transferred from one population to another.
