Earth's minerals have been found in concentrated amounts at the boundaries of tectonic plates: an occurrence that results from the activities at these boundaries. Which statement best explains how minerals become concentrated at these boundaries?

A. Mantle upwelling and downwelling bring various minerals to Earth's surface and, at the same time, take minerals back into Earth's
interior.
B
Minerals from Earth's interior make their way from Earth's core through the layers via convection to Earth's surface and become
concentrated there.
C. Water in Earth's oceans sinks into the crust, becomes hot, and dissolves minerals, these minerals precipitate out as water cools
upon escaping Earth's interior at plate boundaries,
D
Hot water from Earth's interior gushes out; dissolved minerals precipitate out of the water as it cools, and this helps to concentrate
Earth's minerals in various locations over Earth's surface.
