which best explains why a crystal is incompressible?
○ its molecules remain in position without vibrating.
○ the molecules of a crystal behave like those of a gas.
○ there is little, if any, space left between its adjacent molecules
○ its molecules switch positions when they are compressed.

Explanation:

cannot be pushed closer together, making the crystal incompressible. The other options are incorrect: solid molecules vibrate in place (so A is wrong), crystal molecules do not act like gas molecules (B is wrong), and solid molecules do not switch positions when compressed (D is wrong).
