There are an infinite number of irrational numbers between \(\sqrt{11}\) and \(\sqrt{17}\).
To understand why, consider that between any two distinct real numbers (including irrational numbers), there are infinitely many other real numbers, both rational and irrational. Since \(\sqrt{11}\) and \(\sqrt{17}\) are both irrational numbers and they are not integers, there will be infinitely many irrational numbers between them.
Thus, the correct response is: an infinite number.
