Final answer:
Expect to find a volcano at the border of the Eurasian and Indian plates (label 'A'), a convergent plate boundary conducive to volcanic activity. Thus (option a) is right answer.
Step-by-step explanation:
You would expect to find a volcano at the location labelled 'A' on the map provided. Thus (option a) is right answer.
This is because Location A is at the border of the Eurasian and Indian plates, a region known as a convergent plate boundary, where one tectonic plate is being subducted beneath another. Such areas are prone to volcanic activity due to the melting of subducted material and the rise of magma through the crust to form volcanoes.
Locations B, C, and D, which represent the middle of the North American Plate near the Arctic Ocean, the middle of the Antarctic Plate along the coast of Antarctica, and the middle of the Pacific Plate slightly north of the equator respectively, are not typically known for volcanic activity as they are not at the edges of tectonic plates where subduction occurs.
Volcanoes are less likely to occur away from plate boundaries unless there is a hotspot underneath the plate, as in the case of Hawaii on the Pacific Plate. However, since none of the other locations described are known for being above hotspots or at plate boundaries, they are less likely places to find volcanoes.
