b. the collisions of particles with one another is completely elastic.

Can you please expound on why that would be the answer @chmvijay ?

See if you might have learn  the kinetic theory of gases is based on some assumption 
They assume that the collision between the particle is elastic mean no energy transfer between the particles.

other postulates they made are
 the size of the particle is too small compared to the volume of the gas
this you can understand very easily
