statement 1
the reactance of an ac circuit is zero event though the circuit contain a capacitor and an inductor at series resonance

\mathrm{\left|x_{L}-x_{c}\right|=0}\Rightarrow \mathrm{x_{L}=x_{c}}

\rightarrow Therefore the first first statement is true.
statement 2
\rightarrow The average power delivered by the Source becomes zero for pure inductive or capacitive ckt
\rightarrow The sccond statement is false

The correct option is (3).
