Explanation:

Only statements 1&2 are correct.

• A tectonic plate is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic plates. 

• Continental plates form the Earth's landmasses, while oceanic plates lie beneath the ocean floor. 

• Oceanic plates are composed of denser basaltic rocks and are subducted beneath continental plates at convergent boundaries, as continental plates consist of lighter granitic rocks. 

• Earth's lithosphere is divided into 7 major plates and several minor plates. 

• The Arabian Plate is a minor tectonic plate in the Northern and Eastern Hemispheres, moving northward along with the African and Indian plates. 

• Its collision with the Eurasian Plate has been a major force in mountain formation, contributing to the rise of the Zagros Mountains, Alborz Mountains, Iranian Plateau, Himalayas, and other ranges in Southern Europe and Southeast Asia.  

• The heavy weight of the Zagros Mountains has caused the surrounding land to sink, forming the Mesopotamian sedimentary basin. 

• The Eurasian Plate is a major tectonic plate that covers most of Europe, Russia, and parts of Asia, with boundaries shared with the North American, African, Arabian, Indian, and Sunda Plates. 

• It has a divergent boundary with the North American Plate in the west and moves at an average rate of 0.25 to 0.5 inches per year, pulling Iceland apart at 2.5 cm per year. 

Hence option 2nd is correct.
