Answer: (C) A hot spot
Explanation:
A hot spot is created in the volcanic peaks and it is basically developed over the plume. The mantle plumes are the areas of the up-welling and the hot mantle areas. Magma created by the problem area ascends through the unbending plates in the lithosphere layer.
It produces the dynamic volcano at the surface of the earth. In the mantle area, the hot spot are generated in which the rocks are get melted for generating the magma. The hot spot generated the heat are basically comes from the middle of the earth.

Answer:
Option (C)
Explanation:
The continental drift theory was introduced by Alfred Wegener. He said that the continents moved over the vast ocean surface from one place to another.
He contributed many pieces of evidences in support f this theory, which includes the founding of similar fossil assemblages, similar rocks types in the distant continents, matching of the continental boundaries, but he was not able to explain the main mechanism behind the continental motion.
Due to this, this theory was not accepted by the other scientists and he was criticized by them.
Later, this theory was modified into the Plate tectonic theory which was successful in explaining the mechanism behind the continental motion i.e the formation of convection current in mantle that drives the plates movement.
Thus, the correct answer is option (C).
The true statement about tornadoes in this question is that most
tornadoes form during the afternoon. Most tornadoes form at around 3pm to 6pm
but this can happen any time. A tornado moves in a rotating motion that it
forms a tunnel like structure. Tornadoes are often called Twisters.
