Best answer
Correct answer is (a) True

Best explanation: Yes, this is a true statement. Thermionic emission is the process of electron emission involving the liberation of electrons from an electrode by virtue of its temperature and this is done by releasing the energy supplied by heat. This happens as the thermal energy given to the charge carrier overcomes the work function of the material.
