B) 27
C) 5
D) 33

The total degrees of freedom (df) is N - 1, which is 32 in this case. 
The df for treatments (SSTr) is I - 1, which is 5. 
Therefore, the remaining df for error (SSE) is: dfSSE = dfTotal - dfSSTr = 32 - 5 = 27. 
Thus the correct answer is B, which represents 27 degrees of freedom for SSE.
