For the circuit diagram shown, $X$ is a variable resistor, and its resistance may be adjusted from $5.0\,\Omega$ to $500\,\Omega$. The e.m.f. of the battery is $12.0\,\text{V}$. It has negligible internal resistance. What is the greatest range of values of potential difference across the output?
- A$1.3\,\text{V}$ to $11.1\,\text{V}$
- B$1.3\,\text{V}$ to $12.0\,\text{V}$
- C$1.5\,\text{V}$ to $11.1\,\text{V}$
- D$1.5\,\text{V}$ to $12.0\,\text{V}$
