Two junction diodes one of germanium (Ge) and other of silicon (Si) are connected as shown in figure to a battery of emf 12V and a load resistance 10kΩ. The germanium diode conducts at 0.3V and silicon diode at0.7V. When a current flows in the circuit, then the potential of terminal Y will be

12 V
11 V
11.3 V
11.7 V
