A is correct as the ray bending towards the positive plate proved the presence of negatively charged particles in the cathode ray. 
B is correct as the discovery of cathode rays led to the discovery of electrons. 
C is correct as the behavior of the ray was independent of the metal used, proving that all metals contain electrons. Therefore, all three statements are correct, making D the best choice.
