The following arrangement consists of an ideal transformer and an attenuator which attenuates by a factor of 0.8. An AC Voltage VWX1 = 100 V is applied across WX to get an open circuit voltage VYZ1 across YZ. Next, an ac voltage VYZ2 = 100 V is applied across YZ to get open circuit voltage VWX2 across WX. Then, $$\frac{{{{\text{V}}_{{\text{Y}}{{\text{Z}}_1}}}}}{{{{\text{V}}_{{\text{W}}{{\text{X}}_1}}}}},\,\frac{{{{\text{V}}_{{\text{W}}{{\text{X}}_2}}}}}{{{{\text{V}}_{{\text{Y}}{{\text{Z}}_2}}}}}$$ are respectively

A. $$\frac{{125}}{{100}}{\text{ and }}\frac{{80}}{{100}}$$
B. $$\frac{{100}}{{100}}{\text{ and }}\frac{{80}}{{100}}$$
C. $$\frac{{100}}{{100}}{\text{ and }}\frac{{100}}{{100}}$$
D. $$\frac{{80}}{{100}}{\text{ and }}\frac{{80}}{{100}}$$
