Answer
Choice B.
Work Step by Step
On the graph that is given, a vertical line represents a constant voltage.
We see that as the temperature rises from $25^{\circ}C$ to $150^{\circ}C$, we move up the vertical line from the pink curve to the purple curve, resulting in an increased current.
This result is consistent with what we found in the last problem, Passage Problem 42.57.
