Answer: C
These meteorites are the achondrites.
Achondrites are stony meteorites without chondrules. They are igneous rocks, basalts, cumulates and breccias, formed by melting and differentiation on their parent bodies and later knocked off by impacts. The HED group (howardites, eucrites and diogenites) is linked to the asteroid Vesta, and other achondrites come from the Moon and Mars.
Enstatite is a pyroxene mineral (it also names the enstatite chondrites). Carbonaceous chondrites are unmelted, primitive meteorites, not igneous ones. Ignimbrites are terrestrial volcanic rocks deposited by pyroclastic flows.
