Function templates are useful when you want to write a function that can work with multiple data types. If the implementation details of the function are independent of the data types of the parameters, then a function template can be used to write a single function that works with multiple data types. This can save time and reduce the amount of code that needs to be written. Option B is incorrect because not all functions need to be function templates. Option C is incorrect because two different functions can have different implementation details and still not require a function template. Option D is incorrect because function templates are not limited to only being used with functions that have the same type of parameters.
