The answer would be c.cooling on earth's surface. I think they should have a more simpler answer like: cooling very quickly, but, oh well ;)! Hope this answers ur question, all you guys out there suffering through earth science!
Ultramafic igneous rock.
igneous rocks usally form by cooled magma.
most likely as a liquid
sedimentary

Glassy igneous rocks cool the fastest. The most likely had more nucleation. Pegmatic cooled the slowest, which is why its crystals are larger than 1 cm. Phaneritic is the next slowest in cooling. Porphyritic has slow then rapid cooling, while aphanitic igneous rocks also have rapid cooling.

Most igneous rocks would likely contain a varying amount of iron.
study island cheater! : The igneous rock will be weathered and form sedimentary rock.
Igneous rock
Igneous.
sedimentary
It is most likely intrusive
welded tuff is a igneous rock so it is more likely for it to have the same minerals as most other igneous rocks.
