Final answer:
All African lions belong to the same species, Panthera leo, and variations among them are examples of genetic diversity within the species.
Step-by-step explanation:
The question asks if all African lions are the same species. The correct answer to the student's question is A) Yes. All African lions belong to the same species, which is scientifically known as Panthera leo. While there may be variations, such as in color or size, due to different habitats and environmental factors, these lions do not differ enough to be classified as separate species. The observed differences within a species are examples of genetic diversity, which contributes to the biodiversity within a species. It is important to note that while male lions may compete for mating rights, this is behavior within the single species and does not indicate separate species.
