A capacitor \( C=100 \mu \mathrm{F} \) is connected to three resistor each of resistance \( 1 \mathrm{k} \Omega \) and a battery of emf \( 9 \mathrm{~V} \). The switch \( S \) has been closed for long time so as to charge the capacitor. When switch \( S \) is opened, the capacitor discharges with time constant
(a) \( 33 \mathrm{~ms} \)
(b) \( 5 \mathrm{~ms} \)
(c) \( 3.3 \mathrm{~ms} \)
(d) \( 50 \mathrm{~ms} \)
