Some properties of catalysts are:
1. A catalyst improves the speed of a reaction.
2. A catalyst takes part in the reaction even though it will not be consumed or used up in the course of the reaction.
3. A catalyst makes the reaction faster by giving an alternative path with lower activation energy.
4. In a reversible reaction, a catalyst accelerates the reaction in both directions. Therefore, the inclusion of a catalyst will not change the equilibrium point.
Thus the only the third statement is true.
The correct option is C.
