The correct answer is D) Antarctic Plate.

The Earth’s lithosphere is divided into several large and small tectonic plates. Major plates are generally considered to be the Pacific Plate, North American Plate, Eurasian Plate, Indo-Australian Plate, African Plate, South American Plate, and Antarctic Plate. Minor plates are smaller and often located in complex zones between major plates. The Cocos Plate, Nazca Plate, and Caroline Plate are all classified as minor or intermediate-sized tectonic plates. The Antarctic Plate is one of the seven principal major tectonic plates.

Minor plates include the Arabian Plate, Caribbean Plate, Scotia Plate, Philippine Sea Plate, Fiji Plate, and many others. The classification into “major” and “minor” can sometimes vary slightly depending on the source, but the Antarctic Plate is universally recognized as a major plate due to its large size and significant tectonic boundaries.
