This is an exercise. I think there's nothing wrong in this sentence.

Well, if it's an exercise and you think that they are all correct, then that is the answer you should give.

Exercises are supposed to test what you know, now what we know.

Give your answer, then check the exercise answers and see if you are right. If you are right, then that's great. If you are wrong and you don't understand why you are wrong, then come back to us to see if we can explain.
