what determines how much, if any, of a solute is dissolved?\napplication\nequality\nsaturation\nsalinity

Brief Explanations:

In chemistry, saturation refers to the point at which a solution has dissolved the maximum amount of solute it can hold under given conditions. Application and equality are not relevant factors in determining solute - dissolution amount. Salinity is a measure of the amount of salt in a solution, not a general determinant of solute dissolution.

Answer:

C. saturation
