17.answer b-d please

(6%) Problem 17: A bank of batteries, total emf & = 4.5 V, is connected with resistor R = 120 k$2, capacitor C = 470 pF, and two-pole switch S as shown. The switch is initially set to point b so that the R resistor and capacitor are in series. The switch is left in this position for a sufficiently long time so that the capacitor is completely discharged.
