The image shows a circuit with a diode and resistor. A diode allows current to flow only in one direction (forward bias). Here, the diode is reverse biased (cathode positive, anode negative), so it acts as an open switch. Therefore, no current flows through the circuit. With zero current, the voltage drop across the resistor (V = IR) is also zero. Thus, the entire input voltage appears across the diode itself.

The output voltage A is: $Vout=0V$

Final Answer: The first option (0V)
