The circuit shown includes a battery, a high-resistance voltmeter and four fixed resistors. The battery provides an electromotive force (e.m.f.) of $15.0\,\text{V}$ and has negligible internal resistance. What value is indicated by the voltmeter?
- A$3.0\,\text{V}$
- B$6.0\,\text{V}$
- C$9.0\,\text{V}$
- D$12.0\,\text{V}$
