Answer

Brief Explanations:

Martin mixed sulfur and iron filings, which is a physical mixing process. Then he separated them using a magnet, which is a physical separation method. No chemical reaction (like replacement or synthesis) occurred, and there was no change in state of the substances. It was just a process of mixing and separation.

Answer:

B. mixing and separation
