The Correct Option is D

Solution and Explanation

Concept:
A solution is a homogeneous mixture of two or more substances. It consists of:
  • Solvent = component present in larger amount
  • Solute = component present in smaller amount
Solutions are classified according to the physical states of solute and solvent.
Step 1: Nature of gasoline
Gasoline (petrol) is a homogeneous mixture mainly containing:
  • Pentane
  • Hexane
  • Heptane
  • Octane
  • Other liquid hydrocarbons
All these components are liquids under ordinary conditions.
Step 2: State of solvent and solute
Since gasoline is formed by mixing liquid hydrocarbons: \[ \text{Solvent} = \text{Liquid} \] \[ \text{Solute} = \text{Liquid} \] Thus it is a liquid-in-liquid solution.
Step 3: Check options
  • Liquid in Liquid \quad $\checkmark$
  • Liquid in Solid \quad $\times$
  • Solid in Liquid \quad $\times$
  • Gas in Liquid \quad $\times$

Step 4: Final Answer
Gasoline is an example of: \[ \boxed{\text{Liquid as solute and liquid as solvent \] Quick Tip:
Mixture of miscible liquids like alcohol + water or hydrocarbons + hydrocarbons gives liquid-liquid solution.
