Explanation:

If 1 = A...that doesn't work, because Question one is not answer B.
If 1 = B...that doesn't work, because Question one is B...
If 1 = D, then 2 = B, which means 4 = A. If that is true, then 3 = D and 5 = D...but that can't be true, since question 1's answer is not A. Therefore 1 != D.

So 1 = C. This means 3 = B.
If 2 = A...Then 4 = D, but that can't be, since 4 is D.
If 2 = B...Then 4 = A, but that can't be, since there aren't 3 answers left to be D
If 2 = C...Then 4 = B, but that can't be true, because there aren't 2 answers left to be D
So 2 = D, This means 4 = C
If 5 = D, that doesn't work, because now answer 4 is wrong
If 5 = A, that doesn't work because 3 = B
If 5 = C, that doesn't work, because there aren't 3 answers that are B
So 5 = B

Final answer: 1=C, 2=D, 3=B, 4=C, 5=B
