Quizplus · Accepted Answer

The graph in Choice C shows a typical current vs. voltage behavior for a pn junction. At low voltages, the current is negligible. As the voltage is increased, the current increases exponentially until it reaches a saturation value at high voltages. The other choices do not show this characteristic behavior.
