A micrometer screw gauge is used to determine the diameter of a copper wire. The measurement taken with the wire in place is shown in diagram 1. The wire is then taken out and the jaws of the micrometer are closed. The updated reading is shown in diagram 2. Determine the diameter of the wire.
- A$1.90\,\text{mm}$
- B$2.45\,\text{mm}$
- C$2.59\,\text{mm}$
- D$2.73\,\text{mm}$
