Concept:Liquids are nearly incompressible fluids that have a definite volume but no fixed shape.
Explanation:A liquid cannot be easily compressed because its particles are closely packed, yet they can slide past one another.
This matches the property given in statement I: liquids are incompressible.
Since the particles are free to move within the liquid, a liquid takes the shape of the part of the container it occupies.
This matches the property given in statement IV: liquids assume the shape of their container.
Liquids do not have a fixed shape of their own, and they are not highly compressible.
Therefore, statements that describe liquids as having a fixed shape or being easily compressible are false.
Thus, only statements I and IV are correct.
Answer:C. I and IV only
