A current source sends a current `I=(i_0) cos (omegat)`, When connected across an unknown load, it gives a voltages output of `v=v_(0)sin [omega t+(pi//4)]` across that load. Then the voltage across the current source may bebroaught in phase with the current through it by

connecting an inductor in series with the load

connecting a capacitor in series with the load

connecting an inductor in parallel with the load

connecting a capacitor in parallel with the load.
