The correct answer is Option B.
IS SUPPOSED TO BE is used when something is believed to be the case, but is not necessarily so.
In the given sentence, the speaker believes that the seminar is interesting but isn't sure of the same.
Thus Option B is the correct answer.
The remaining options are incorrect because:
USED TO BE is used to refer to a habit or trend.
MUST HAVE BEEN is used to express certainty.
NEED TO BE expresses requirement.
