The correct answer is A. Hydrated Aluminosilicate.
Zeolites are aluminosilicate minerals with a framework structure made up of SiO4 and AlO4 tetrahedra. The tetrahedra share oxygen atoms to form a three-dimensional network. The pores in the zeolite framework can be filled with water molecules or other ions. Zeolites are used in a variety of applications, including water treatment, catalysis, and separations.
Option B is incorrect because hydrated calcium sulfate is a mineral called gypsum. Gypsum is a white, soft mineral that is used in a variety of applications, including plaster, drywall, and cement.
Option C is incorrect because dehydrated aluminosilicate is not a mineral. Aluminosilicate is a general term for a class of minerals that contain aluminum and silicon.
Option D is incorrect because dehydrated calcium sulfate is not a mineral. Calcium sulfate is a general term for a class of minerals that contain calcium and sulfur.
