The volcanic plateau among the given options is "Deccan". A volcanic plateau is a large, flat, and elevated landform that is formed from the accumulation of volcanic material over time. Deccan plateau is located in India and is one of the largest volcanic plateaus in the world, covering an area of over 500,000 square kilometers.
The Deccan plateau was formed by a series of volcanic eruptions that occurred millions of years ago. The lava flows from these eruptions spread out over a large area, and over time, they cooled and solidified, forming a thick layer of basaltic rock. The plateau is also characterized by many volcanic features, such as cones, vents, and fissures.
The other options listed are not volcanic plateaus. Kukuruku is not a known geological feature, Terra Rosa is a type of soil, Graben is a type of geological structure, and Atlas is a mountain range.
