Answer
Option (iv) is correct.

Explanation

  • In solids, particles are closely packed and fixed in place.
  • In liquids, particles are close but can move past each other.
  • This is why liquids flow but solids keep their shape.
Solid particles are closely packed and fixed; liquid particles can move past each other.
