Option 3 : Both 1 and 2

The correct answer is Option 3, i.e Both 1 and 2.

Particles of matter intermix on their own with each other.
They do so by getting into the spaces between the particles.
This intermixing of particles of two different types of matter on their own is called diffusion.
There’s a force that acts on the particulate matter that keeps it together.
Some substances change into powder, some others change into small crystals and others don’t break easily.
The magnitude of the force of attraction varies from matter to matter, i.e. depends on the nature of the matter.
For example, breaking chalk is easier than breaking a nail. This proves that attraction varies from particles of one substance to another.
Cohesion means the force of attraction between the particulate matter of the same substance.
