The correct answer is: A. Dipped in a nickel sulphate solution.
When a spoon is to be electroplated with nickel, the spoon is dipped in a nickel sulphate solution. The spoon becomes the cathode, and a pure nickel rod becomes the anode. A direct current is passed through the solution, and the nickel ions in the solution are attracted to the spoon. The nickel ions are deposited on the spoon, and the spoon becomes coated with nickel.
Option B is incorrect because the spoon is not made the anode. The anode is the electrode where oxidation occurs. In this case, the nickel rod is the anode, and the nickel ions are oxidized and released into the solution.
Option C is incorrect because the spoon is not made the cathode. The cathode is the electrode where reduction occurs. In this case, the spoon is the cathode, and the nickel ions are reduced and deposited on the spoon.
Option D is incorrect because the spoon is not coated with nickel sulphate and dried. The spoon is dipped in a nickel sulphate solution, and the nickel ions are deposited on the spoon. The spoon does not need to be coated with nickel sulphate or dried.
