The correct answer is B. Seamount, guyot, atoll.
The seamount represents an underwater mountain that occurs as consequence of volcanic activity, occasionally they get above the surface of the water and create islands (Hawaii, Iceland). After some time, the erosion cause the island to dissolve and get back under water, the water will flatten it's top, and that is actually the formation of the guyot. Once the guyot is formed, on it's top a coral colony will start developing and little by little make a circle shaped island, which represents the formation of the atoll.
