Which of the following is true of salt lakes?

a. The water flowing in to salt lakes comes directly from the ocean. b. Salt lakes are formed when river bends are cut off. c. The water flowing in to salt lakes contains minerals. d. Salt lakes do not experience shrinking due to erosion.

The best answer here is c. The water flowing in to salt lakes contains minerals. Also of course the presence of the water in the lake may dissolve out underlying salts into solution in the water of the lake. When such a mineral rich body of water evaporates this then leaves behind the salt lake feature.
