Verified Correct Answer: B.
Grammar & Contextual Explanation
When you say you are allergic "to" something, it means that thing causes an allergic reaction in you. In this case, dust is the cause of the allergic reaction, so the correct preposition to use is "to." If you were allergic "with" dust, it would imply that dust is somehow accompanying or connected with your allergy, which doesn't make sense in this context.
