In a given transformer for a given applied voltage, which losses remain constant irrespective of load changes?

In a given transformer for a given applied voltage, which losses remain constant irrespective of load changes? Correct Answer Hysteresis and eddy current losses

Hysteresis and eddy current losses are voltage and frequency dependent losses that too from primary side thus, load change will not make any effect on these losses and they will remain constant as long as voltage and frequency is constant.
