Answer: Option (a) is the correct answer.
Step-by-step explanation:
In a liquid state, particles are held less tightly as compared to a solid state. So, they have some kinetic energy due to which they collide with each other.
As a result, particles of a liquid are able to slide past each other. Hence, they are able to acquire the shape and volume of a container in which they are poured.
Whereas when particles of a liquid can break free from one another and spread out then it means a substance is present in a gaseous state.
When the particles of a liquid can vibrate within their fixed locations then it means the substance is present in a solid state. And, they have definite shape and volume.
Thus, we can conclude that a liquid take the shape of the bottom of its container as the particles of a liquid can flow around one another to new locations.
