The given graph shows variation with time in the source voltage and steady state current drawn by a series RLC circuit :-

Which of the following statements is/are correct?
(a) Current lags the voltage
(b) Resistance in the circuit is $250\sqrt{3} \mathrm{\Omega }$
(c) Reactance in the circuit is $250 \mathrm{\Omega }$
(d) Average power dissipation in the circuit is $20\sqrt{3} \mathrm{\Omega }$

Box may have any series combination of L, C and R.

The graph shows current v/s voltage in a series RLC A.C. circuit. The arrow indicates the direction that this curve is drawn as time progresses. In this plot, the
                          

In the L-C circuit shown in figure, the current is in direction shown in the figure and charges on the capacitor plates have sign shown in the figure. At this time :-
