As an electron makes a transition from an excited state to the ground state of  a hydrogen like atom/ion   (a) kinetic energy, potential energy and total energy decrease    (b) kinetic energy  decreases, potential energy increases but total  energy  remains same    (c ) kinetic energy and total energy decrease but potential energy increases    (d) its kinetic energy increases but potential energy and total energy decrease
