The best interpretation of the information presented in your question is option:
d: When molten material exits the crust, it cools to form new rock which means the youngest/newest rocks are produced on the surface.
This statement reflects the geological principle that igneous rocks, which form from molten material (magma), are typically the newest rocks on the planet's surface as they cool and solidify after being erupted from volcanoes. Over time, older rocks may be eroded and buried, while younger rocks are formed from the cooling of lava.
