Both 1st and 2nd

• C.

A substance which does not mix with water.

• D.

None of the above

C. A substance which does not mix with water.
Explanation
Insoluble substances are those that do not mix with water. They cannot dissolve or form a homogeneous mixture with water. This is because the molecules of the substance do not have the necessary polarity or attractive forces to interact with the water molecules. Instead, insoluble substances tend to form separate phases or precipitates when mixed with water.

A. A substance which mixes with water
Explanation
Soluble objects are substances that can dissolve or mix with water. This means that when they are added to water, they will break down and become evenly distributed throughout the water, forming a solution. This is in contrast to substances that do not mix with water, which will remain separate and not dissolve when added to water. The correct answer, "A substance which mixes with water," accurately describes soluble objects.
