The correct answer is option (d) A- Solid; B- Liquid; C- Gas.
Explanation:
- Solid has the least inter molecular space as the particles are very tightly packed and there's no space for the movement.
- Liquid has more inter molecular space solids than solid as its particles are loosely packed as compared to solids.
- Gases have the most inter molecular space as its particles are very loosely packed.
