Solution

The correct option is B A(Q,S,T); B(R,S,T); C(P,T), D(Q,S,T)
(A)

on increasing $w, z$ increases so current decrease (B)

Current and voltage in same phase if $X_{L} = X_{C}$ and potential across capacitor is in opposite phase with potential across-inductor
(C)
Current leads applied voltage on increase $w$ . The impedance decreases so current increases
(D)
Current lags behind applied voltage when $X_{L} > X_{C}$ and potential across capacitor is in opposite phase with potential across inductor
