Some of the modern ohmmeters have a diode test setting. If you do not have one of these ohmmeters then to test the diode you need to check its resistance in the forward and the reverse direction. These resistances should be ().
A. relatively high in the forward direction and relatively low in the reverse direction
B. relatively low in the forward direction and relatively low in the reverse direction
C. relatively low in the forward direction and relatively high in the reverse direction
D. relatively high in the forward direction and relatively high in the reverse direction
