2)  The particles always travel in a straight line until they collide with another particle or the walls of the container.
3) Particles are of smaller size as compared to the distance between particles.
4) There exist minimal/no force of attraction between the gas particles neither there exist attractive interaction between the particles and the walls of the container.
5) Collisions between gas particles or with the walls of the container are  elastic in nature. 

Thus, statement a i.e. </span><span>Gas particles have a high force of attraction to one another or to the walls of the container contradicts the postulates of kinetic theory of gases</span>
