Which of the scenarios would most likely lead to allopatric speciation? A. A population of mussels inhabits a rocky shoreline. Most individuals live on rocks close to the water where they remain wet. A few individuals have adapted to dry conditions and inhabit the less crowded rocks higher up on shore. B. A single plant in a population of sunflowers produces diploid gametes that have two sets of chromosomes instead of the normal one set of chromosomes. Although it cannot reproduce with other plants in the population, it can self-fertilize to produce viable seeds. C. In an archipelago, a few members of a moth population on one island are carried by the wind to a neighboring island, where they form a subpopulation. D. In a population of swordtail fish, females prefer to mate with males with the longest tails
