Diode in small signal positive halfwave rectifier circuit acts as Correct Answer Ideal diode

The diode acts as an ideal diode, since the voltage across the ON diode is divided by the open loop gain of the op-amp. As the input voltage starts increasing in the positive direction, the output of the op-amp also increases positively till the diode become forward biased.
