Which of the following is NOT one of the seven continents?

The correct response is C, as Atlantis is not recognized as one of the seven continents. It is a legendary island first mentioned by the philosopher Plato, who described it as a powerful and advanced civilization that ultimately sank into the ocean. The concept of Atlantis has captured the imagination of many, leading to various theories and stories, but it is not a geographical landmass that exists today.

In contrast, Africa, Antarctica, and South America are all defined continents, each with distinct geographical boundaries, ecosystems, and cultural histories. Africa is known for its diverse landscapes and rich wildlife, Antarctica is predominantly a frozen expanse that serves as a habitat for various species and a site for scientific research, and South America is home to diverse cultures and geography ranging from rainforests to mountains. Thus, understanding continental classification is vital for geographical literacy.
