Final answer:
Sympatric speciation is the process of new species arising in the same location, and it can occur in a single generation. Various mechanisms can lead to sympatric speciation, including changes in behavior, mating preferences, or genetic mutations.
Step-by-step explanation:
Sympatric speciation is the process by which a new species arises within the same location or habitat without the need for geographic isolation. This means that sympatric speciation can occur in a single generation, which makes option C the correct statement. There are various mechanisms that can lead to sympatric speciation, such as changes in behavior, mating preferences, or genetic mutations that result in reproductive isolation. One example of sympatric speciation is the formation of different species of cichlid fish in African lakes, where each species has adapted to different feeding niches and mating behaviors.
