Answer from: palomaresmitchelle

Material A is mineral, material B is a rock, material C is a mineral and material D is a rock.

Explanation:

A mineral is a natural substance that generally is solid while rocks are made of a combination of different minerals, besides rocks are characterized by its texture, origin and composition while minerals are characterized by its hardness and color.

According to this definition we can appreciate that material A is only made of one material and it is characterized by its color so we can conclude that it is a mineral. Material B is composed by two materials so it is a rock. Material C is characterized by its color and appearance and it is made of the same elements, with this information we conclude that material C is a mineral. Material D is made of different elements and is characterized by its porosity texture what lead us to classify it as a rock.
