<u>Answer:
</u>
Neither rock A nor B could become metamorphic rocks.
<u>Explanation:
</u>
- 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".
