What is resonant circuit?

In a resonant LCR circuit,

The series resonant circuit is called as

Mark the incorrect option 1) When an uncharged capacitor is connected across the battery, just after the connections has been made, it behaves as short circuit 2) When capacitor is fully charged it behave as short circuit 3) When capacitor is fully charged it is behaving as open circuit 4) (A) & (C) both.

In series resonant circuit, at resonance,
