Answer:
Hey there!! to answer your question, let me tell you what a mixture is, and some examples of it.
What is a mixture?
Ans. A mixture is a mix of 2 or more different components or substances without any chemical change or change in the form of the molecules. It is basically 2 or more substances mixed together in any ratio and there is no new substance formed.
What are some examples of a mixture?
Ans. Salt and pepper, water and salt.
Notice that in these mixtures, they can still be separated using physical methods , and there wont be a new substance formed when they are mixed together.
Explanation:
So, following the definition of a mixture, let us answer your question :
Which one of the following will result in the formation of a mixture?
A) Crushing of a marble tile into small particles
B) Breaking of ice cubes into small pieces
C) Adding sodium metal to water wrong
D) Adding milk in water.
Ans. Option A) Is wrong as when a marble tile is crushed into small pieces, there is no other substance mixed along with it. So, it cant be called a mixture, since a mixture is a mix of 2 or more substances , whereas this has only one substance in it, thus it cant be called a mixture.
Option B) Is wrong as when an ice cube is broken into small pieces, there is no other substance mixed along with it. So, it cant be called a mixture, since a mixture is a mix of 2 or more substances , whereas this has only one substance in it, thus it cant be called a mixture.
Option C) Is wrong as when we add sodium metal to water, it results in a chemical change with a new substance formed. The molecules of the 2 substances react chemically to form a new substance . thus, it cant be called a mixture as A mixture is a mix of 2 or more different components or substances without any chemical change or change in the form of the molecules. But , in the above case, there is a change in molecules, thus it is a chemical change and not a physical one.
Option D) Is right as when we add milk to water, they still can be separated by a physical method, that is filtration . There is no change in the molecules of the substances and there is no new substance formed, so they have reacted physically, thus it is a mixture as A mixture is a mix of 2 or more different components or substances without any chemical change or change in the form of the molecules. The above case exactly fits this definition, thus it is a mixture.

Answer: d) Adding milk in water
Explanation:
A mixture is a substance that is formed when two or more different substances are physically mixed and they do not chemically react to form a new substance.
a) Crushing of a marble tile into small particles
This will not result in the formation of a mixture because here, there is only one substance present. For a mixture to be formed, there must be at least two substances present.
b) Breaking of ice cubes into small pieces
Again, this will not form a mixture because here also there is only one substance present.
c) Adding sodium metal to water
Here, there are two substances present. But, when we add sodium in water, they chemically react to form a new substance. In a mixture, there shouldn't be any chemical reaction as when two substances chemically react, there is a change in the molecular structure.
d) Adding milk in water
This will form a mixture as when we add milk in water, two substances are being mixed and there is no chemical reaction happening.
