Why does no DC current flow in the primary winding of the output transformer of class B push-pull amplifier?

a) Because DC currents from both transistors flow in opposite directions
b) Because the net impedance is very high to allow flow of current
c) The winding only allows AC current to flow
d) Current only flows in secondary winding due to the presence of load at that side
