{'matter intermix': [0, 0, 0, 1], 'particles': [1, 0, 5, 16], 'force': [0, 0, 0, 2], 'matter': [0, 0, 1, 0]}

The correct answer is option 3: Both 1 and 2.

Statement I is true. Particles of matter do intermix on their own. This is known as diffusion, which is the spontaneous movement of particles from an area of high concentration to an area of low concentration. This process occurs naturally in gases, liquids, and solids.

Statement II is also true. Particles of matter have forces acting between them. These forces can be attractive or repulsive, depending on the nature of the particles. For example, in solids, particles are held together by intermolecular forces, which give the solid its shape and structure. In fluids (liquids and gases), particles experience various forces such as gravity, electrostatic forces, and van der Waals forces.

Therefore, both statements I and II are correct. The particles of matter do intermix on their own and they have forces acting between them.
