The Correct Option is D
Solution and Explanation
Step 1: At $t=0$, an inductor acts as an open circuit and a capacitor acts as a short circuit.
Step 2: At $t=\infty$, an inductor acts as a short circuit and a capacitor acts as an open circuit.
Step 3: Substitute these conditions into the resistive network to calculate equivalent resistance and solve for $I = E/R_{eq}$.
Step 4: For this standard circuit, the calculated values match option (D).
