Hint: Before we proceed into the problem, it is important to know the definition of Le Chatelier’s principle.
The system returns to its initial equilibrium state as a result of a net reaction that happens when an equilibrium condition is disturbed. Le Chatelier’s principle explains how a system reacts when its equilibrium is changed. According to this, if any of the variables that control a system's equilibrium circumstances change, the system will adapt in order to lessen the impact of the change.

Complete answer:Le Chatelier's principle states that the reaction will proceed to minimize the impact of concentration variations if the equilibrium is upset by the addition or removal of any reactant or product.
By shifting the direction of the net reaction in the direction that consumes the additional substance, the concentration stress of an added reactant or product is eliminated.
The exothermic reaction produces the required heat.
\[A + B →C + D\]
Le Chatelier's principle states that when the temperature drops, the reaction will move in a way that will release heat and negate the effect of the temperature drop.
Because of this, the reaction will advance by lowering the temperature.
Therefore, Low temperature facilitates the progression of exothermic reactions.
Therefore, the reaction may be made to proceed forward by decreasing the temperature.

Hence, the option C is correct

Note: Students should always remember the exact concept of some principles and laws. A movement in the equilibrium's location counteracts the effect of a change in one of the variables that characterizes a system at equilibrium. This is crucial, especially for industrial applications where it's crucial to predict and maximize yields.
