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

Choose the correct answer from the options given below:

• A. A-IV, B-I, C-III, D-II
• B. A-I, B-IV, C-II, D-III
• C. A-III, B-I, C-IV, D-II
• D. A-I, B-II, C-IV, D-III

Answer 1

The Correct Option is B

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.
