The Correct Option is A
Solution and Explanation
${ Al_2(SO_4)_3 -> 2Al^{3+} + 3SO^{2-}_{4}} ,i = 5$
${K_4[Fe(CN)_6] -> 4K^+ [Fe(CN)_6]^{4-} ,} i = 5$
${NaCl - > Na^+ + Cl^-,} i = 2$
${Al(NO_3)_3 -> Al^{3+} + 3NO^- _3,} i = 4$
${ Na_2 SO_4 - > 2Na^+ + SO_4^{2-} } i = 3$
${K_4[Fe(CN)_6] -> 4K^+ [Fe(CN)_6]^{4-} ,} i = 5$
${NaCl - > Na^+ + Cl^-,} i = 2$
${Al(NO_3)_3 -> Al^{3+} + 3NO^- _3,} i = 4$
${ Na_2 SO_4 - > 2Na^+ + SO_4^{2-} } i = 3$

Solutions
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
Types of Solutions:
The solutions can be classified into three types:
- Solid Solutions - In these solutions, the solvent is in a Solid-state.
- Liquid Solutions- In these solutions, the solvent is in a Liquid state.
- Gaseous Solutions - In these solutions, the solvent is in a Gaseous state.
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
- Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
- Saturated Solution- A solution in which no solute can be dissolved after reaching a certain amount of temperature is known as an unsaturated saturated solution.
- Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
