b. Fe, Mg, and Ca

Explanation:

In an ultramafic magma, there is concentration of Fe, Mg and Ca in the melt. An ultramafic magma is one with less amount of silica content. Ultramafic magma are usually rich in iron bearing minerals, magnesium and calcium. These minerals are usually the first to crystallize out in a melt when rocks are heated.
