Options:
(a) At `t=pi/(2omega)` , instantaneous power supplied by source is negative.
(b) From `0 < t <(2pi)/(3pmega)` , average power supplied by source is positive.
(c) At `t=(5pi)/(6omega)` , instantaneous power supplied by source is negative.
(d) If `omega` is increased slightly, angle between the two phasors decreases
