In a parallel RLC circuit, the current through the capacitor and the inductor is given by IC = IC,max*cos(ωt) and IL = IL,max*cos(ωt), respectively. The current through the resistor is given by IR = IR,max*sin(ωt). Therefore, the correct choice is D, as the current through the capacitor is IC = IC,max*cos(ωt).
