Solution

The correct option is D only a fraction of collisions are effective which have enough energy to form products
According to collision theory rate of reaction is proportional to the number of collisions per second. And all the collision will not result in formation of product. Only those collision where molecules have enough activation energy and proper orientation will lead to a chemical reaction.
