(A) Hans Krebs	(I) Citric acid cycle
(B) P. Mitchell	(II) Chemiosmotic hypothesis
(C) W. M. Stanley	(III) C₃ cycle
(D) M. Calvin	(IV) Crystallization of Tobacco Mosaic Virus

Options:

Correct option is C

· Hans Krebs discovered the Citric Acid Cycle (Krebs cycle), which plays a key role in cellular respiration.
· Peter Mitchell proposed the Chemiosmotic Hypothesis, explaining ATP synthesis in mitochondria.
· W. M. Stanley is credited with crystallizing the Tobacco Mosaic Virus (TMV), proving that viruses can be purified.
· Melvin Calvin discovered the C₃ cycle (Calvin cycle), which explains the biochemical pathway of photosynthesis in plants.
