Distinction between a solid and a fluid is made based on the substance's ability to resist an applied shear (tangential) stress that tends to change its shape.
A solid can resist an applied shear by deforming its shape, whereas a fluid deforms continuously under the influence of shear stress, no matter how small its shape is.
A fluid can be defined as a substance capable of flowing and changing its shape according to the surroundings without offering internal resistance. Liquid offers no resistance to change of shape, and it conforms to the shape of its surrounding.

Introduction:
Fluids are a type of substance that can flow and take the shape of any container they are put into. They have many properties that make them unique from solids and gases.
Definition:
The term fluid is applied to substances which offer no resistance to change of shape.
Explanation:
Here are some explanations as to why the correct answer is option 'A':
- Fluids can flow easily and change shape because their molecules are not tightly packed together like they are in solids. This lack of structure allows them to take on any shape and move freely.
- Unlike gases, fluids have a definite volume and do not expand to fill their container. They also have a density that is generally higher than that of gases.
- Fluids can be either liquids or gases. Both types of fluids have the properties of being able to flow and take on the shape of their container.
- Liquids are a type of fluid that has a definite volume but no definite shape. They can be poured and take on the shape of the container they are in. Examples of liquids include water, milk, and oil.
- Gases are another type of fluid that has no definite shape or volume. They can be compressed and expand to fill their container. Examples of gases include air, helium, and carbon dioxide.
Conclusion:
Overall, the term "fluid" is used to describe substances that can flow and take on the shape of their container. They offer no resistance to change of shape because their molecules are not tightly packed together.
