A The direction of the conductor's motion
B The change in magnetic flux that produced it
C The applied electric field

Lenz's Law states that the direction of the induced current (and thus the induced EMF) is such that it opposes the change in magnetic flux that produced it. This is a manifestation of the conservation of energy.
