A practical investigation is done to determine the resistance of a wire. The current in the wire is $(1.0 \pm 0.2)\,\text{A}$ and the potential difference across the wire is $(8.0 \pm 0.4)\,\text{V}$. Calculate the resistance of the wire and its uncertainty.
- A$(8.0 \pm 0.2)\,\Omega$
- B$(8.0 \pm 0.6)\,\Omega$
- C$(8 \pm 1)\,\Omega$
- D$(8 \pm 2)\,\Omega$
