In the circuit shown, when the key \( k \) is pressed at time \( t=0 \), which of the following statements about current \( \mathrm{I} \) in the resistor \( \mathrm{AB} \) is true
(A) \( \mathrm{I}=2 \mathrm{~mA} \) at all \( \mathrm{t} \)
(B) I oscillates between \( 1 \mathrm{~mA} \) and \( 2 \mathrm{~mA} \)
(C) \( \mathrm{I}=1 \mathrm{~mA} \) at all \( \mathrm{t} \)
\( P \)
(D) At \( t=0, I=2 \mathrm{~mA} \) and with time it goes to \( 1 \mathrm{~mA} \)
