Question

igneous rocks are formed___
through cooling magma
by burial and lithification
from metamorphic rocks.

Explanation:

Igneous rocks are formed from the cooling and solidification of magma or lava. Magma is molten rock beneath the Earth's surface, and when it cools (either slowly beneath the surface or quickly on the surface as lava), it forms igneous rocks. Burial and lithification are processes related to sedimentary rocks (not igneous). Igneous rocks can be the precursor to metamorphic rocks (through heat and pressure), but metamorphic rocks are not the starting - point for igneous rocks.

Answer:

Through cooling magma
