Explanation:

Vaalbara, Rodinia, and Pannotia are supercontinents in Earth's geological history. • Vaalbara: Vaalbara is believed to be one of the earliest supercontinents, existing around 3.6 to 2.7 billion years ago during the Archean Eon. It is a supercontinent that is thought to have been located near the South Pole. The evidence for Vaalbara comes from geological and paleomagnetic studies of rocks in parts of present-day Australia, India, and South Africa. • Rodinia: Rodinia is another supercontinent that is thought to have existed around 1.3 billion to 750 million years ago during the Neoproterozoic Era. It was a vast landmass that assembled from smaller continental blocks and later broke apart. Rodinia's existence is supported by geological and paleomagnetic evidence, and it played a significant role in Earth's geological history. • Pannotia: Pannotia is a supercontinent that is believed to have formed approximately 600 million years ago during the late Precambrian period. It is thought to have existed for a relatively short period before breaking apart. Pannotia is an important concept in understanding the geological events that occurred during the late Precambrian. • Hence option (b) is the correct answer.
