Marks: +1, -0

In the circuit shown, initially there is no charge on capacitors and keys S1 and S2 are open. The values of the capacitors are C1=10µF,C2=30µF and C3=C4=80µF

Which of the statement(s) is/are correct?

[JEE Adv 2019 P1]

If key S1 is kept closed for long time such that capacitors are fully charged, the voltage across the capacitor C1 will be 4V.
At time t=0 the key S1 is closed, the instantaneous current in the closed circuit will be 25mA
If key S1 is kept closed for long time such that capacitors are fully charged, the voltage difference between points P and Q will be 10V.
The key S1 is kept closed for long time such that capacitors are fully charged. Now key S2 is closed, at this time, the instantaneous current across 30Ω resistor (between points P and Q) will be 0.2A (round off to 1st decimal place)
