Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Resistance of wire, $R = ρ \frac{1}{A}$
Where $ρ$ is resistivity of material which does not depend on the geometry of wire. Since when wire is bended, resistivity, length and area of cross-section do not change, therefore resistance of wire also remains same.
