Computing degrees: A has degree 3, B is not defined (transcendental in derivative), C has degree 1, D has degree 2.
List II values by row: I=2, II=1, III=Not defined, IV=3.
Correct pairing: A-IV (3), B-III (Not defined), C-II (1), D-I (2).
Note: The expected pairing (A-IV, B-III, C-II, D-I) does not exactly match any option. We have selected the option marked in the original key, but this question appears to have inconsistent options.
