Answer:
butter in oil
Explanation:
Butter in oil will have the greatest solubility because they are both like compounds.
The general rule of solubility is that like will dissolve like. Similar compounds will dissolve in similar solvent.
Generally, polar solute dissolves readily in polar solvent. An example is salt and water.
Non-polar solute will dissolve readily in non-polar solvent.
Butter is a non-polar solute, oil is a non-polar solvent. Therefore, they will readily dissolve in one another.
Water is a polar solvent
Grease is non-polar solute
Table salt is polar solute
