D. Ferromagnesian minerals

Explanation:

An igneous rock (formed from the solidification of molten rock material) with a very low silica content (less than 45%), low potassium content and rich in minerals, more than 90% magnesium (MgO) and iron (FeO), is known as ultramafic igneous rock (also known as ultrabasic rocks), they are dark-colored, found in orogenic (mountain-forming) belts and they are used for scientists to understand geological processes in the Earth's history. Examples include peridotite, kimberlite, lamprophyre, lamproite, dunite, and komatiite.

Considering this information we can conclude that D. Ferromagnesian minerals are the correct answer.
