Respuesta :

The correct answer for the question that is being presented above is this one: "B. a decrease in pressure." At divergent plate boundaries in the ocean, magma rises and melts because of a decrease in pressure. The magma rises and melts as the divergent plate boundaries in the ocean decreased in pressure.
