Answer:
The arrangement of particles is least ordered is a > c > b > d
Explanation:
Given that,
The arrangement of particles is least ordered in a sample of NaCl.
We know that,
The least ordered arrangement are.
The form of state of particle in least ordered.
So, The least ordered arrangement will be
aqua > gas > liquid > solid
The arrangement of particles is least ordered in a sample of NaCl

Hence, The arrangement of particles is least ordered is a > c > b > d
