# Answer for this MCQ on electricity

$R=\frac{V}{I}$

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

R

_{A}> R

_{B}> R

_{C}> R

_{D}

Option (a) is correct.
