Answer:

Neither rock A nor B could become metamorphic rocks.

Explanation:

  • Magma is the molten rock under the surface hardens into igneous rock. This rock breaks down over time under the process of weathering.
  • These pieces of "igneous rocks" are cemented together with other bits of rocks to form sedimentary rocks.
  • These rocks get buried under the geological processes like earthquakes. Now, coming in contact with high temperatures and magma, these rocks get changed into metamorphic rocks.
  • So, from option A, igneous rock is formed. When combined with rock B and other rocks, sedimentary rocks are formed.
  • Metamorphic rocks are formed in the next process. Therefore, neither of the two rocks could become "metamorphic rocks".
