Detailed Solution

Naturally occurring substance and Can be hard and soft are correct statements about minerals.
Minerals are naturally occurring substances that occur through and in nature only and can be extracted through various methods because of industrial and commercial uses. Secondly, minerals can be hard and soft. Heterogeneous in the composition is incorrect and the reason can be the minerals are not heterogeneous in composition, instead, they are homogeneous, meaning they follow a certain path of hardness, luster, color, etc in one rock. And minerals are generally extracted from the pieces of big rocks for further usage, so they can’t be in powdery form. Some major minerals include calcium, phosphorus, magnesium, etc.
