Key evidence for the modern theory of plate tectonics includes the apparent fitting together of continents, mapping of ocean floor features, and magnetic field stripes found in the Atlantic Ocean's floor. These elements demonstrate the movement and interaction of tectonic plates. The correct answer to the question is C.
