In the circuit the input V_i has positive and negative swings. V_o is the output—

1. V_o = 0 for negative V_i
2. V_o = V_R for positive V_i
3. V_o = V_R for V_i > V_R
4. V_o = V_R for all V_i

Correct Option: C

From the given circuit it is clear that the output will appear only when the diode will be in the conducting situation, and it will be possible only when V_i > V_R, than V₀ = V_R.

Hence alternative (C) is the correct answer.
