A population of deer is separated by an emerging volcano. The two populations come back into contact 200 years later, but are incapable of breeding. Which of the following best describes the process that occurred?adaptationspeciationconvergent selectionstabilizing selection

The volcano separated the deer populations, allowing them to evolve independently. After 200 years, they could no longer breed with each other, which means reproductive isolation had developed. The formation of reproductively isolated populations is speciation, so the best answer is speciation.
