At a junction node \(N\) in a circuit, current \(I_1\) flows into the node through branch 1, and current \(I_2\) flows out of the node through branch 2. Due to a small stray capacitive path, charge accumulates on node \(N\) at a rate given by \(\\dfrac{dq}{dt} > 0\). A third branch carries current \(I_3\) out of node \(N\). Which of the following correctly pairs the expression for current \(I_3\) with the explanation of charge conservation at node \(N\)?
