The correct option is C Definite volume but indefinite shape
A liquid is made up of tiny particles held together by the intermolecular force of attraction.
The intermolecular force of attraction in liquids is less than that of solids. Thus, they can flow easily and take the shape of a container. Hence, they do not have a definite shape.
However, the forces are not so weak that the particles can move free of each other. Thus, they cannot expand to fill the volume of the entire container like gases. Hence, liquids have a definite volume.
