Both B and C are wrong grammatically because estoy and soy are conjugated for the first person when it is second person. Both A and D are correct gramatically, A would be stating that you are boring, since Ser describes adjectives and other permanent things, D stating that you are bored, estar describes feelings. A would make the most sense, so A would be the correct answer in the context of the rest of the question.
