Solution

The correct option is C Adding $F_{2}$
According to the Le Chatlier's principle, A system in chemical equilibrium changes towards a new equilibrium when subjected to a change in pressure, temperature, volume, or concentration. The equilibrium shift partly counteracts the change that was applied to the system initially.

Here, as the concentration of $F_{2}$ is increased, the equilibrium shifts towards the opposite side resulting in the formation of $C l F_{3}$

Also, as temperature is increased and the reaction is exothermic, the equilibrium constant value decreases.
