Solution

The correct option is B low pressure and high potential
Low pressure and high potential
In discharge tubes, a high electric field is applied between the two electrodes the medium between them which is a gas at low pressure. Due to the electric field, the gas gets ionized, releasing electrons which moves towards the anode thus constitutng the electric current. A low pressure is required as at high pressure the movement of electron will be retarded due to collision with nucleus / atoms of gas.
