Correct answer is (a) 3mA

Explanation: In ideal diode model the diode is considered as a perfect conductor in forward bias and perfect insulator in reverse bias. That is voltage drop at forward bias is zero and current through the diode at reverse bias is zero. Since diode is forward biased current

I = (3V/1K) = 3mA.
