Answer: Option (b) is the correct answer.
Explanation:
In solids, atoms are held together because of strong intermolecular forces of attraction between them.
As a result, solids have a definite shape and volume. Hence, its molecules are not able to slide past each other.
Whereas in liquids, molecules are together by less strong forces as compared to solids. Therefore, liquids do not have fixed shape and volume. They occupy the shape of a container in which they are kept together.
Therefore, molecules of a liquid are able to slide past each other.
In gases, molecules are held by weak Vander waal forces. So, they collide rapidly and occupy the volume of container and not the shape. Similarly, plasma is a hot ionized gas which consists of positive ions and negative electrons. Like gases, plasma also occupies the volume of a container.
Thus, we can conclude that liquid is the matter which can fill a container from top to bottom.

BY The Editors of Encyclopaedia Britannica | View Edit History
ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms. Examples of these processes include the reaction of a sodium atom with a chlorine atom to form a sodium cation and a chloride anion; the addition of a hydrogen cation to an ammonia molecule to form an ammonium cation; and the dissociation of a water molecule to form a hydrogen cation and a hydroxide anion.
