Which population in the chart below has the best chance for survival in a rapidly changing environment?

I believe the answer is population 1
Population 1 in the chart has the best chance for survival in a rapidly changing environment. It reproduces sexually, ensuring that the population maximizes variation caused by genetic recombination. The population's short life span and large number of offspring ensures that several large generations can be produced in a short time frame. In combination, these reproductive characteristics help to maximize the ability of the species to adjust and evolve in the face of changing environmental conditions would be slow as compared to population 1.
