Correct Answer: Electrons


Solution : The correct option is Electrons .

Cathode rays are a beam of electrons. They were first observed in the late 19th century in cathode ray tubes, and their discovery played a crucial role in the development of modern physics. The cathode rays are negatively charged particles (electrons) that are emitted from the cathode (negative electrode) in a vacuum tube and travel towards the anode (positive electrode).
