| B. | (incremental change in resistance due to strain/resistance of an unstretched wire)*(unstretched length of wire/incremental change in length) |
| C. | (incremental change in resistance due to stress/resistance of an unstretched wire)*(incremental change in length/unstretched length of wire) |
| D. | (resistance of an unstretched wire/incremental change in resistance due to stress)*(unstretched length of wire/incremental change in length)l |
