• B. The density of a solid is highest whereas that of gases is lowest

• D. Molecules of a solid possess vibratory motion

Answer 1

The correct option is C Gases possess definite volumes like liquid

Gases are the third state of matter in which molecules do not have any force of attraction between them.

Hence, at normal room temperature gases are not visible and they do not have fixed volumes like solids and liquids.

Hence, the correct option is C.
