The answer is letter B. Pangaea is the name of the supercontinent. There are many other recorder supercontinents such as Laurasia, Euramerica, Gondwana, Pannotia, Rodinia, Nuna, Ur and Vaalbara. However, for the purpose of this question we are going to talk about Pangaea. It was said that the supercontinent Pangaea existed during the late Paleozoic and early Mosezoic eras and it incorporated almost all the landmasses here on Earth such as South America, Africa, Antarctica, India and Australia.
However, it began to break apart during the Early Jurassic Epoch about 200 million years ago which eventually formed the modern continents and the Indian and Atlantic oceans. The idea of its existence was proposed by Alfred Wegener, a German meteorologist, in 1912 wherein he explained the theory of continental drift.
