The correct answer is A. From Duccan Trap.
The Deccan Trap is a large volcanic province that covers much of the Deccan Plateau in central and western India. It is one of the largest basaltic provinces in the world, covering an area of about 500,000 square kilometers. The Deccan Trap was formed by a series of volcanic eruptions that occurred over a period of about 60 million years, beginning in the Cretaceous period. The eruptions were caused by the subduction of the Indian Plate beneath the Eurasian Plate.
The Deccan Trap is composed of a variety of basalts, including tholeiitic basalts, alkali basalts, and andesite basalts. The basalts are typically dark in color and have a fine-grained texture. They are also very hard and dense, making them a good building material.
The Deccan Trap is an important geological feature because it provides evidence for the breakup of the supercontinent Gondwana. The eruptions that formed the Deccan Trap occurred at the same time that the Indian Plate was rifting away from the African Plate. The Deccan Trap is also an important economic resource because it contains large deposits of iron ore, manganese ore, and bauxite.
The other options are incorrect because they do not refer to the Deccan Trap. The Cuddapah Trap is a geological formation in southern India that is composed of sedimentary rocks. The Dharwar Trap is a geological formation in central India that is composed of volcanic rocks. Unclassified Crystallation is a term used to describe rocks that have not been classified into a specific type.
