Match List I (line coding scheme) with List II (average bandwidth, N = data rate). List I: A. NRZ-L, B. 2B1Q, C. 4D-PAM5, D. MLT-3. List II: I. B = N/4, II. B = N/8, III. B = N/3, IV. B = N/2.

1. AA-II, B-I, C-IV, D-III
2. BA-IV, B-II, C-I, D-III
3. CA-IV, B-I, C-II, D-III
4. DA-III, B-IV, C-II, D-I
