The Correct Option is B
Solution and Explanation
Initial molarity-
$=\frac{10.6}{106} \times \frac{1000}{ V ( ml )} $
$=\frac{10.6}{106} \times \frac{1000}{100}=1 M$
Now, $M _{1} V _{1}= M _{2} V _{2}$
$1 \times 10= M _{2} \times 1000$
$M _{2}=\frac{10}{1000}$
$M _{2}=10^{-2} M$

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.
