Hint:The particles of matter have several properties like the space between them, attraction force, movement due to kinetic energy, etc. Particles of gases move at high speed due to the maximum free spaces available between particles. Solids on the other hand have least property of diffusion due to fixed volume and fixed shape.

When we mix two different types of matter like we mix sugar and water, we obtain a sugar solution in which sugar is evenly distributed among the particles of water and if we mix sand in water we get a heterogeneous solution but still particles of sand manage to occupy space among the particles of water. This justifies that particles of matter have enough space between them. The extent of space present between the particles depends on the state of matter whether it is solid, liquid or gas.
At room temperature, particles of matter exchange heat with surrounding and due to this they possess some kinetic energy and this kinetic energy of particle increases with increase in temperature of surrounding. Due to this kinetic energy, particles of matter are continuously moving about their mean position.
Matter exists in three states namely solid, liquid and gas. These states of matter arise due to the variation in the characteristics of the particles of matter. Solids have definite shape, fixed volumes, tendency to maintain their shape and are rigid. Strength of force acting between particles of solid is so strong which helps solid to have such properties. On the other hand, liquids have no fixed volume but have a fixed volume as they take the shape of a vessel in which they are filled. The rate of diffusion of liquids is higher than that of a solid because the liquid particles can move freely because of greater space between them and lesser force of attraction between particles as compared to solid. Gas particles move randomly at very high speed due to the maximum free space between the particles and minimum force of attraction among them. Gases are highly compressible and gases show the property of diffusing maximum.

Thus, the correct option is A.

Note:
Matter is defined as an object or substance that has mass and which can be felt by any of our five senses. Example: air, food, stone, cloud, water, sand, etc. All the matters are made up of particles. The size of particles in a matter is extremely small as a few masses of matter can have millions of tiny particles.
