Solution
The correct option is B Cathode rays
If the pressure in a discharge tube is reduced to 10−4mm, then cathode rays (rays of electrons) come out, perpendicular to the cathode surface .Due to very low pressure, electrons can easily reach to the target without any deflection due to gas molecules.Anode rays or Canal rays travel from anode through the cathode holes to the tube wall. X-rays are generated by the reverse photo electric effect, in which photons are produced by electrons.
