E Correct answer
Explanation

Correct answer. In 1960, Hill and Bendal suggested Z-scheme of light reaction. In 1961, Peter Mitchell proposed chemiosmotic hypothesis of ATP synthesis in light reaction. In 1966, Hatch and Slack reported the C4 pathway for CO2 fixation in certain tropical plants. In 1954, Melvin Calvin traced the path of carbon in photosynthesis and gave the C3 cycle (now known as Calvin cycle).
