In the circuit shown below, a voltmeter with resistance $R_V$ and an ammeter with resistance $R_A$ are connected to determine the resistance $R$ of the fixed resistor. Which condition is required if an accurate value of $R$ is to be found?
- A$R$ is much smaller than $R_V$.
- B$R$ is much smaller than $R_A$.
- C$R$ is much greater than $R_V$.
- D$R$ is much greater than $R_A$.
