D Correct answer
Explanation

Mica is predominantly found in both igneous and metamorphic rocks, occurring as sheets or flakes due to its perfect basal cleavage. While quartz and pyroxene are common in igneous rocks, and amphibole in metamorphic rocks, mica is distinctive for being abundant in BOTH rock types. Biotite and muscovite are the two most common mica minerals.
