Which of the following statements describes the particle arrangement and motion within a liquid?

You did not list any statements but just look for the one that something like the particles in a liquid can freely move around and don't really have a definite structure or arrangement.  It does however have a definite volume.

I hope that helps. 
If you have any questions feel free to ask them in the comments.
