Solution

The correct option is D Change in temperature
The equilibrium constant is not changed by changing the concentration of the reactant or by changing pressure.
It is also not affected by a change in the amount of catalyst.
The only thing that affects equilibrium constant is the change in temperature. The resultant effect depends upon whether the given reaction is exothermic or endothermic.
