Accepted Answer

The correct option is A because of the specific chemical applications of each potassium salt:

Potassium bromide is historically used in photography as a restraining agent in developing solutions to prevent fogging.

Potassium nitrate, also known as saltpeter, is a primary oxidizing ingredient in gunpowder.

Potassium sulphate is commonly used as a high quality synthetic fertilizer because it provides both potassium and sulfur to plants.

Mono potassium tartarate, often called cream of tartar, is used in the bakery industry as a leavening agent and to stabilize egg whites.

Matching these pairs leads to the sequence I B, II D, III A, and IV C.
