The correct answer is: Are electrons emitted by cathode and travelling towards anode
Cathode rays are a beam of electrons emitted from the cathode of a high vacuum tube.
Cathode rays are negatively charged and hence they move towards positively charged ions hence they move towards anode.
Therefore the correct option is (2).
