The following arrangement consists of an ideal transformer and an attenuator which attenuates by a factor of $0.8$. An ac voltage $V_{WX1}=100V$  is applied across $WX$ to get an open circuit voltage $Y_{YZ1}$ across $YZ$. Next, an ac voltage$V_{YZ2}=100V$  is applied across $YZ$ to get an open circuit voltage $V_{WX2}$ across $WX$. Then,$V_{YZ1}/V_{WX1}$,  $V_{WX2}/V_{YZ2}$ are respectively,
1. $125/100$  and  $80/100$
2. $100/100$  and  $80/100$
3. $100/100$  and  $100/100$
4. $80/100$   and  $80/100$
