Options
- AA - 1, B - 2, C - 3, D - 4
- BA - 2, B - 1, C - 4, D - 3
- CA - 3, B - 4, C - 1, D - 2
- DA - 4, B - 2, C - 3, D - 1
Correct answer
D. A - 4, B - 2, C - 3, D - 1
Step-by-step solution
A - 4: The overall equation for photosynthesis is CO₂ + H₂O + Light → [CH₂O] + O₂. B - 2: T.W. Engelmann used a prism to identify the action spectrum of photosynthesis by detecting oxygen evolution. C - 3: Cornelius van Niel showed that photosynthesis involves light-dependent reactions and that in green plants, water is the hydrogen donor. D - 1: Julius von Sachs demonstrated that plants produce glucose which is stored as starch.
