Detailed Solution

Concept- It is known that the maximum voltage across capacitor is equal to maximum voltage across Inductor.
Now, according to the maximum power transfer theorem the power on both the components should be equal therefore voltage of both the components should be equal.
As per question given that,
Max. charge on capacitor = Question ImageIn LC circuits, maximum voltage across capacitor is equal to maximum voltage across Inductor.
So, maximum voltage of capacitorQuestion Image=maximum voltage of inductorQuestion ImageQuestion ImageTherefore, the value ofQuestion ImageHence, the correct option is (1).
