The correct option is Nazca plate.
Explanation
According to the Theory of Plate Tectonics, the Earth's lithosphere is divided into seven major plates and several minor plates. The classification is primarily based on the size of the tectonic block.
Analysis of Options:
- Antarctica and the surrounding oceanic plate Antarctica and the surrounding oceanic plate: This is classified as a major plate. It encompasses the continent of Antarctica and the surrounding ocean floor.
- India-Australia-New Zealand plate India-Australia-New Zealand plate: This is classified as a major plate. It includes the Indian subcontinent, Australia, and the surrounding oceanic regions.
- Nazca plate Nazca plate: This is classified as a minor plate. It is an oceanic plate located in the eastern Pacific Ocean basin, situated between the South American plate and the Pacific plate.
- Pacific plate Pacific plate: This is the largest tectonic plate and is classified as a major plate. It is almost entirely oceanic.
Key Takeaway:
The seven major plates are Antarctica, North America, South America, Pacific, India-Australia-New Zealand, Africa, and Eurasia. Important minor plates include the Nazca, Cocos, Arabian, Philippine, Caroline, and Fuji plates.
