Four capacitors of capacitance `C`, `2C`, `3C` & `4C` respectively are connected as shown in figure. Battery is deal and all the connected wires have no resistance capcitance or inductance. Initially the switch `S` is open. If at `t=0` switch `S` is closed
Heat generated is the switch after closing switch is
A. `(CE^(2))/(105)`
B. `(2CE^(2))/(105)`
C. `(CE^(2))/(5)`
D. `(CE^(2))/(35)`
