Answer:
A. Gases do not have a definite volume.
Step-by-step explanation:
A perfume is a gaseous substance. In a bottle, the gases have been compressed under high pressure so as to take up a little volume. One very important property of gases is that, they do not have a definite volume. They simply assume the volume of their containers. When the perfume is released, it simply begins to spread around through the process of diffusion so as to fill the volume of room.
