The best declaration for a mutator function to allow the user to change the age would be a void function with the name setAge and a single integer parameter newAge. This would allow the user to easily set the age of the Wine object to a new value. Option A is a getter function, not a mutator function. Option B is not a valid function declaration. Option C is a good name for a mutator function, but it needs a parameter to actually change the age value.
