Solution

The correct option is A

E must be connected to H and F to G


Correct option is A: E must be connected to H and F to G

Explanation:

  1. Positive metal ions, such as copper(II), deposit in a negative charge electrode layer on the cathode.
  2. metal which is to be electroplate should be connected to the cathode and another electrode to be connected with the anode.
  3. E must be connected to H and F to G

Hence option A is correct
