True, but much, much faster. If you take a bar of pure copper and a bar of pure iron, and clamp them together in a vice and let them sit for a week or two, you'll find atoms of copper half an inch in the iron, and atoms of iron half an inch in the copper. It's totally amazing, and not what i'd expected. But when you get a Mechanical Engineering degree, they don't let you play with computers 24x7, they also make you take materials science classes. The answer your teacher is looking for is B) FALSE.
