Evaporate minerals, or “salts,” include halite, anhydrite, and
a) gypsum
b) silica
c) calcium carbonate
d) siliceous ooze

The right option is; a) gypsum

Evaporate minerals, or “salts,” include halite, anhydrite, and gypsum.  

Evaporite minerals are minerals found in the sediments of soluble salts that forms from the evaporation of water. The evaporation may take place in the sea or in shallow basins on land. Salts are transported from land surfaces to the sea by rivers. There is precipitation of the salts when seawater evaporates. The salts then settle at the bottom of the sea and they are deposited based on the degree of their solubility. Evaporate minerals or salts include gypsum, halite (common salt) and anhydrite
