The diagram shows two resistor networks. [diagram: network 1 with resistor R in series with parallel combination of two 2R resistors; network 2 with resistor 2R in series with parallel combination of two R resistors] What is the ratio (total resistance of network 1)/(total resistance of network 2)?

1. A4/5
2. B5/4
3. C1/2
