Answer: B) Solutes
Step-by-step explanation:
Binary solution is a homogeneous mixture of two components called as solute and solvent.
Solute is the component which is present in smaller proportion and is solid for solid in liquid solution and solvent is the component which is present in larger proportion.
If a liquid is dissolved in a liquid, it is called as emulsion.
If a solid is dissolved in a liquid, it is called as solid solution.
Thus gasoline being in larger quantity and cleaning or anti knock additives in smaller quantities, they are respectively termed as solvent and solute.
