Option B is correct since, the output of the D FF follow's the input i.e for CLK=1
i/p D=O o/p Q=0,
i/p D=1 o/p Q=1.
If you see the options, option B is incorrect because it's not following the i/p properly.
i/p D=O o/p Q=0,
i/p D=1 o/p Q=1.
If you see the options, option B is incorrect because it's not following the i/p properly.
