 Answer the question below. Please respond with the option letter (A, B, or C) first. (HINT: Each PubMedQA instance is composed of (1) a question which is either an existing research article title or derived from one, (2) a context which is the corresponding abstract without its conclusion, (3) a long answer, which is the conclusion of the abstract and, presumably, answers the research question, and (4) a yes/no/maybe answer which summarizes the conclusion.) 

Question:
Do foreign bodies migrate through the body towards the heart?

[2025-09-25T11:54:50.281011] [PI reasoning] **Considering foreign body migration**

I’m trying to determine if foreign bodies migrate through the body toward the heart. I know there's an article about this topic. It seems like previous studies might suggest there's no clear directional migration, even though myths exist about needles reaching the heart. There’s also a paper by Lambert that I can’t quite recall. I definitely need to look that up fast to get clearer answers.

I've found that the article states foreign bodies can't migrate towards the heart, so option B is correct. The instructions specify that I need to provide the option letter first, which I will ensure to do. I'll simply say, "B." I might also consider adding a brief explanation if needed, possibly referencing the authors from 2009. For now, I'll stick to the essential answer and see if any additional citation is required later.
