A Correct answer
Explanation

Magma is molten rock beneath Earth's surface that contains minerals in dissolved form. As magma cools and solidifies, minerals crystallize and concentrate, forming mineral deposits. The sea floor, mountain ridges, and continental plates are locations where minerals might be found, but magma is the primary source from which minerals originate.
