We can't use 'this' in a static method because the keyword 'this' returns a reference to the current instance of the class containing it. Static methods (or any static member) do not belong to a particular instance. They exist without creating an instance of the class and are called with the name of a class, not by instance, so we can’t use this keyword in the body of static Methods. However, in the case of Extension Methods, we can use the parameters of the function.
