# Answer for this MCQ on electricity

Dear Student

Here the slope is given by $\frac{I}{V}$ So its slope will give 1/R.
Hence more the slope less the value of Resistance hence is the best conductor.
The decreasing order of slope is  D>C>B>A
Therefore the decreasing order of resistance is as follows
RA> RB> RC> RD
Option (a) is correct.
