B) are compressible.
Explanation:
The three members of the noble gas family are all compressible in nature and they are monoatomic gaseous molecules.
There are three states of matter which are:
Solid
liquid
Gases
Gases are random matter that have not fixed shape and volume. This implies that they can easily fit into any container they are placed into. Their state of motion is randomized and they are free to move in all directions colliding with one another and the walls of their container.
When pressure is applied to them, they get compressed and takes up the shape of any vessel they are in.
Gases are the only compressible state of matter.

To create the Lewis structure we need to take into account the octet rule: atoms tend to gain, lose or share electrons to complete their valence shell with 8 electrons.
C belongs to Group 4A in the periodic table so it has 4 valence electrons. It needs to share 4 pairs of electrons to complete the octet.
F belongs to Group 7A in the periodic table so it has 7 valence electrons. Each F needs to share 1 pair of electrons to complete the octet.
As a consequence, in CF₄, C will form a single bond with each F and all the octets will be complete.
Within a physical change, an element can change forms, such as going from solid to a liquid through melting. Color change can also occur during a physical change. Physical changes are very different from chemical changes. In a chemical change the element itself changes into something else within a reaction, such as combustion (burning).
