. When the key K is pressed at time t = 0, which of the following statements about the current I, in the resistor AB of the given circuit is true


A. It is 2 mA at all times

B. It is oscillates between 1 mA  and 2 mA

C. It is 1 mA at all times

D. At t = 0,  I =  2 mA and with time it finally reduces to 1 mA
