Solution

The correct option is B 2 and 3 only
Capacitors consist of two metallic plates. One plate of the capacitor is positively charged, while the other is negatively charged.
Capacitor stores electrical energy between its plates. Dielectrics are used between the plates of the capacitors.
Hence, statements 2 and 3 are correct.
