C Correct answer
Explanation

Since the sentence is distinguishing between two symptoms and diseases, so 'distinguishes' should be followed by 'between' which is not present in options (A) and (B), (E) uses the word 'among' which is also incorrect as among is used for more than 3 things, 'between' should always be followed by 'and' as a grammar rule, so (C) is the correct option.
