A copper wire of length L and cross sectional Area A is used and the corresponding current Vs voltage graph is drawn as shown.The slope of the curve becomes

$(a)\; \text{more if experiment is performed at level temperature} \\(b)\;\text{more if length of wire is increased }\\(c)\;\text {less if length of wire is increased }\\(d)\; \text{none of the above } $

Can you answer this question?

The slope of the graph represents $\large \frac{I}{V}=\frac{I}{R}$
As length of wire increases the resistance of wire increases and so slope of the curve decreases .
Hence c is the correct answer.
