Correct Answer: Option A
Explanation

When cathode rays are deflected onto the electrode of an electrometer, the instrument becomes negatively charged. Cathode rays are streams of fast-moving electrons that are negatively charged. When they are deflected towards a positive electrode, it demonstrates that they are negatively charged. This is because opposite charges attract each other.
