Explain why bending a wire does not affect its electrical resistance?

Assertion (A): Bending of a conducting wire effects electrical resistance. Reason( R): Resistance of a wire depends on resistivity of that material.

If 'n' is the number of free electrons in a metallic wire, then the resistance is proportional to
