"A" would not work, because "ExecuteResult" is too late. "D" would break the existing authentication. But "B" and "C" should work i guess. So my answer is "B" and "C".

I agree the same. Correct answer is c and d. B is uncorrect. Because Authentication and authorization in ASP.NET life cycle are in events handled by HTTP Module. HTTPHandler are meant to handle filetype or request endpoint not for authorization.
