Correct Option: (b) Explanation:  Pair 1 is incorrect: Cocos plate - Between Central America and Paci fi c plate  Pair 2 is correct: Nazca plate - Between South America and Paci fi c plate  Pair 3 is incorrect: Capricorn microplate - Between Indian and Australian plates  Pair 4 is correct: Caroline plate - Between the Philippine and Indian plate Supplementary notes: Tectonic plates  A tectonic plate (also called lithospheric plate) is a massive, irregularly-shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.  The lithosphere includes the crust and top mantle with its thickness range varying between 5-100 km in oceanic parts and about 200 km in the continental areas.  Plates move horizontally over the asthenosphere as rigid units.  A plate may be referred to as the continental plate or oceanic plate depending on which of the two occupy a larger portion of the plate.  Paci fi c plate is largely an oceanic plate whereas the Eurasian plate may be called a continental plate.  The major plates are as follows : (i) Antarctica and the surrounding oceanic plate (ii) North American (with western Atlantic fl oor separated from the South American plate along the Caribbean islands) plate (iii) South American (with western Atlantic fl oor separated from the North American plate along the Caribbean islands) plate (iv) Paci fi c plate (v) India-Australia-New Zealand plate (vi) Africa with the eastern Atlantic fl oor plate (vii) Eurasia and the adjacent oceanic plate.  Minor plates - Cocos plate : Between Central America and Paci fi c plate (ii) Nazca plate : Between South America and Paci fi c plate (iii) Arabian plate : Mostly the Saudi Arabian landmass (iv) Philippine plate : Between the Asiatic and Paci fi c plate (v) Caroline plate : Between the Philippine and Indian plate (North of New Guinea) (vi) Fuji plate : North-east of Australia. New plates map  The new model for tectonic plates better explains the spatial distribution of 90 percent of earthquakes and 80 percent of volcanoes from the past two million years.  Existing models only capture 65 percent of earthquakes.  The map includes several new microplates to the existing tectonic plate model like the  Macquarie microplate which sits south of Tasmania; and  The Capricorn microplate which separates the Indian and Australian plates.  Researchers found that plate boundary zones account for nearly 16% of the Earth’s crust and an even higher proportion, 27%, of continents.  The new model now includes all the deformation zones north of India as the plate bulldozes its way into Eurasia.
