In a particular region, a species of lizard lives in the lowlands. Even though there are numerous mountains in the region, the climate on the mountains is too cold for the lizards to survive. Scientists are concerned that the lowlands will become much warmer by the end of the twenty-first century and will become unsuitable for this lowland lizard species. Which of the following best predicts the impact on the lizard species if there is a gradual increase in the average temperatures found in both the lowlands and mountains in this region?

A. Some lizards will migrate to new habitats in the mountains and become isolated, leading to allopatric speciation.
B. The species will undergo artificial selection, as the genes will adapt to warmer temperatures.
C The species will experience a genetic bottleneck, and sympatric speciation will result in thedevelopment of several new species.
D The lizards will hybridize with a different lizard species that is adapted to a warmer environment, leading to increased genetic variation in the species.
