The correct answer is B. Extrusive Igneous
Explanation
The image shows an image of an Obsidian rock and at the top a text fragment that says "The photo below shows a sample of Obsidian forms when lava from a volcanic eruption cools very quickly aboveground"
Igneous rocks are a group of rocks that includes all those that have been formed by the solidification of magma or lava expelled from the earth's lithosphere through a process called crystallization. In general, when the solidification of magma occurs within the lithosphere, the resulting rock is called intrusive. On the other hand, if the cooling occurs (at least in part) at the surface or a shallow depth, the resulting rock is called extrusive.
Taking into account the text that complements the image of the question and the previous information, it is possible to affirm that the correct answer is B. Extrusive Igneous because the rock is the result of the solidification of lava above the ground.
