Because both the technician says correct that is the returnless fuel system use both of the techniques which is by the use of transistor or by the use of the width modulation by which they control fuel pump.

PWM(Pulse Width Modulation) can work by pulsates the direct current and the other ways by which it works.

So, the other options are false because both are true.
