Unfortunately the report filter screen only supports the logical AND operator. There is an existing tracker item to add support for the OR operator. Given the constraints of the problem, that a respondent can only select one answer, I believe you can create the appropriate filter by negating your logic. Additionally I have made the assumption that question is required. For example:
(1 OR 2 OR 3 OR 4)
could be rewritten as
(!5 AND !6 AND !7 AND !8... AND !15) Note: ! indicates is not equal to.
