I can definetely take out A. and B.  im just confused whether it should be inorganic or organic

Well, they can have stuff from organics in them, BUT, it must fully decompose, etc.  So even though the calcium in the sea from critter shells is at one time organic, it is NOT seen as organic by the time it makes it onto minerals.

That s why they say minerals are 100% inorganic material.
