The Correct Option is A
Solution and Explanation
0.5 M $H_2SO_4$ = 1 N $H_2SO_4$
$ {$\underset{\mathrm{(conc)}}{ {N_1V_1}}$ = $\underset{\mathrm{(dil)}}{ {N_2V_2}}$}$
1 N $\times$ 1 L = $N_2 \times $ 10 L
$N_2$ = 1/10 N = 0.1 N.

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.
