I think its B it sounds more right than the others

Zaiden Hudson · Answer 2

The answer is A because minerals are what make up an object, in this case, a rock. And since you asked for a definition this is the closet because it includes lava rocks and gravel. Also, a rock can be more than one mineral and it doesn't have to be magnetic. Also, it is the build up of minerals, not the breakdown.
