check current input and output of the previous time slot.

And it is edge triggered. and D flipflop hence output = D.

at first edge, input = 1, output of prev cycle = 0 , and output in current state goes high, hence equation must be D.Q'

Not sure yet,

at second edge input still 1, prev cycle output = 1, and current cycle output goes low. Hence D.Q' is again followed.

Answer should be option C.
