Answer 2

The correct Statement is Both Rock A and Rock B are igneous rocks. Thus, option 1st is correct.

What is Igneous rock?

Igneous Rock refers to the formation of the rock through the cooling of the molten lava that comes out from the volcano and reaches to the earth surface.  

The formation of the igneous rock takes place when magma i.e. molten rock, either at volcanoes on the surface of the Earth or when the melted rock is still inside the crust, cools and crystallizes, igneous rocks are created.

Due to the extreme heat present in the upper mantle or lower crust, all magma forms underground. In the given scenario, the rocks are formed in the same manner, i.e. through the molten magma.

Therefore, it can be concluded that the type of the rock A and rock B belongs to the category of igneous rock. Hence, option 1st is correct.
