Select correct statement for a capacitor having capacitance C,is connected to a source of constant emf E 

Strain energy in the capacitor must increases even if the capacitor had an initial charge

Almost whole of the energy supplied by the battery will be stored in the capacitor, if resistance of connecting wire is negligibly small

Energy stored depends on type of the source of emf 

Energy received by the capacitor will be half of energy supplied by the battery only when the capacitor was initially uncharged
