Text Solution
Verified by ExpertsThe correct answer is:
C
We know that, V-I curve for a linear device is a straight line passing through origin. Due to some errors/carelessness on the part of experiment all points may not come on the same line. In this situation, we draw the most appropriate curve.
From the diagram, 
.
