| List-I | List-II |
| A. ETS Complex I | I. NADH Dehydrogenase |
| B. ETS Complex II | IV. Succinate Dehydrogenase |
| C. ETS Complex III | II. Cytochrome bc1 |
| D. ETS Complex IV | III. Cytochrome C oxidase |
The correct matches for the electron transport system (ETS) complexes and their associated enzymes are:
A. ETS Complex I - I. NADH Dehydrogenase
B. ETS Complex II - IV. Succinate Dehydrogenase
C. ETS Complex III - II. Cytochrome bc1
D. ETS Complex IV - III. Cytochrome C oxidase
Therefore, the correct option is (2): A-I, B-IV, C-II, D-III.
