b. shallow sea
c. fast moving stream
d. coastline

Option (B)

Explanation:

Rock salt is commonly known as the halite whose chemical formula is NaCl and gypsums are also soft minerals, forming large colored crystals and are commonly found to be present in association with the rock salt and sulfur deposits. They are also comprised of impurities such as sylvite and sometimes potassium is also found to be present in the form of a mineral. They are formed due to the evaporation of salt water that is mainly made up of dissolved ions namely Na+ and Cl-. They are found mainly in the shallow marginal seas, bays, and estuaries and in the dry lake beds.

Thus, the most likely place for the rock salt and gypsum to occur is the shallow sea.
