Igneous rocks are formed by the cooling of the magma.
Sedimentary rocks are formed by weathering and erosion of igneous rocks and then consolidation of the sediments.
Metamorphic rocks are formed when igneous or sedimentary rocks are subjected to heat and pressure.
The metamorphic rocks melts and forms magma which in turn cools down to form igneous rocks.
So, we see that the rocks that have magma as a phase of transformation is igneous and metamorphic.
Hence the answer is
E. igneous rock to metamorphic rock
