Hint:Electric circuits are closed-loop or path systems that consist of a network of electrical components through which electrons can pass. This route is constructed with electrical wires and is operated by a battery.

Complete answer:
When the electrodes are immersed in water and current is passed through the water, bubbles of oxygen and hydrogen form, according to William Nicholson, a British chemist. He found that on the electrode connected to the negative terminal, hydrogen bubbles formed, while on the electrode connected to the positive terminal, oxygen bubbles formed. Chemical reactions occur in a conducting solution as an electric current passes through it. The chemical effect of electric current is what it is called.

Chemical reactions occur as an electric current passes through a conducting solution. As a consequence, gas bubbles may form on the electrodes. Metal deposits can be seen on electrodes. It is possible that the color of the solution will change. What solution and electrodes are used will determine the reaction.

Electricity does not conduct through all liquids. Regardless, some liquids are decent conductors of electricity and others are poor conductors. Water containing dissolved salts and minerals is a strong conductor of electricity, whereas distilled water is not.

If the water is purified and no lemon juice is used, there will be no current in the circuit. This is due to the lack of dissolved salts in distilled water, which enable it to conduct electricity. If the water is salty, a weak current can flow through the circuit, producing bubbles on the negative electrode.

So, the answer is option D.

Note:The constituents break down into negative and positive ions as electricity is passed through water combined with various substances. An electric current flows through these ions. The better the conductor of electricity, the more ions there are.
