Minerals may form on earth’s surface when
a. magma heats a solution.
b. crystallization is delayed.
c. solutions evaporate.
d. pure metals are present

The correct answer is option C; solutions evaporate

Explanation:

A mineral is formed when the solution in which it is dissolved just evaporates leaving behind magma for crystallization. The solution containing large amount of dissolved solid is warmed in an open container and  the solvent  is allowed to evaporate thereby leaving behind   a saturated solution which on further evaporation leads to the production of crystals
