Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Bending a wire does not change length or cross section area , hence resistance remains same.
$R = ρ \frac{L}{A}$ , Resistance is proportional to resistivity .
Both are correct but reason in not the correct explanation.
